Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear nanophotonics is a rapidly developing field of research that aims at detecting and disentangling weak congested optical signatures on the nanoscale. Sub-wavelength field confinement of the local electromagnetic fields and the resulting field enhancement is achieved by utilizing plasmonic near-field antennas. This allows for probing nanoscopic volumes, a property unattainable by conventional far-field microscopy techniques. Combination of plasmonics and nonlinear optical microscopy provides a path to visualizing a small chemical and spatial subset of target molecules within an ensemble. This is achieved while maintaining rapid signal acquisition, which is necessary for capturing biological processes in living systems.Herein, a novel technique, wide-field surface enhanced coherent anti-Stokes Raman scattering (wfSE-CARS) is presented. This technique allows for isolating weak vibrational signals in nanoscopic proximity to the surface by using chemical sensitivity of coherent Raman microspectroscopy (CRM) and field confinement from surface plasmons supported on a thin gold film. Uniform field enhancement over a large field of view, achieved with surface plasmon polaritons (SPP) in wfSE-CARSS, allows for biomolecular imaging demonstrated on extended structures like phospholipid droplets and live cells. Surface selectivity and chemical contrast are achieved at ~ 70 fJ/mum2 incident energy densities, which is over five orders of magnitude lower than used in conventional point scanning CRM.Next, a novel surface sensing imaging technique, local field induced metal emission (LFIME), is introduced. Presence of a sample material at the surface influences the local fields of a thin flat gold film, such that nonlinear fluorescence signal of the metal can be detected in the far-field. Nanoscale nonmetallic, nonfluorescent objects can be imaged with high signal-to-background ratio and diffraction limited lateral resolution using LFIME. Additionally, structure of the extended samples' surfaces can be visualized with a nanoscale axial resolution providing topographic information.Finally, a platform for coherently interrogating single molecules is presented. Single-molecule limit SE-CARS on non-resonant molecules is achieved by means of 3D local field confinement in the nanojunctions between two spherical gold nanoparticles. Localized plasmon resonance of the dimer nanostructure confines the probe volume down to 1 nm3 and provides the local field enhancement necessary to reach single-molecule detection limit. Nonlinear excitation of Raman vibrations in SE-CARS microspectroscopy allows for higher image acquisition rates than in conventionally used single-molecule surface enhanced Raman spectroscopy (SERS). Therefore, data throughput is significantly improved while preserving spectral information despite the presence of the metal. Data simultaneously acquired from hundreds of nanoantennas allows to establish the peak enhancement factor from the observed count rates and define the maximum allowed local-field that preserves the integrity of the antenna. These results are paramount for the future design of time resolved single-molecule studies with multiple pulsed laser excitations, required for single-molecule coherence manipulation and quantum computing.
Book Synopsis Nanophotonic Devices for Modulation and Enhanced Raman Spectroscopy by : Herman Man Kai Wong
Download or read book Nanophotonic Devices for Modulation and Enhanced Raman Spectroscopy written by Herman Man Kai Wong and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanophotonic devices, which typically rely on metal nanostructures that support surface plasmon polaritons, have been demonstrated to provide sub-wavelength confinement of light down to the nanoscale and thus achieve superior enhancement of local electromagnetic (EM) fields. A wide range of applications that can benefit from nanophotonics have been proposed. In this thesis, we investigate the use of several representative nanophotonic structures to design devices that can improve performance in two specific applications: (1) modulators based on the phase change material vanadium dioxide (VO2) and (2) enhanced Raman spectroscopy. As well, conventional dielectric based photonic devices are designed to provide proof-of-concept experimental demonstrations for: (A) all-optical VO2 modulator with planar integration of both control and signal beams, and (B) broadband orthogonal coupler bend to interface between dielectric wire and slot-type waveguides. These dielectric devices serve as bases for future implementations using more advanced nanophotonic structures as presented in this thesis. First, a unique hybrid plasmonic waveguide functionalized with VO2 to form a modulator, in which the electric-field distribution within the waveguide cross-section can be engineered precisely, is shown to exhibit enhanced performance compared to implementation using the silicon wire waveguide. It is also one of the smallest modulator designs proposed to date that features amongst the highest extinction ratio and optical bandwidth. For the application to enhanced Raman spectroscopy, first an artificial hyperbolic material, which consists of a multilayer stack of ultra sub-wavelength alternating metal and dielectric layers, to construct nano-dimers for surface-enhanced Raman spectroscopy is investigated. Although the novel nanophotonic device provides much enhanced local EM fields and photonic density of states in comparison to pure metal nanoresonators, the increased absorption leads to overall reduced Raman enhancement factors for molecules located within their near-fields. Finally, pure metal, hybrid, and hyperbolic material plasmonic slot waveguides are studied for enhancing Raman scattering in a regime where both strategies of EM field enhancement and increase in light-matter interaction volume (as well as improved delivery of excitation light and collection of Raman scattered signal) are employed. The nanoscale plasmonic slot waveguides attain much higher Raman enhancement compared to optofluidic photonic crystal fibers, and thus they are suitable when ultra-low analyte volume is required in a portable instrument.

Book excerpt: Current developments in optical technologies are being directed toward nanoscale devices with subwavelength dimensions, in which photons are manipulated on the nanoscale. Although light is clearly the fastest means to send information to and from the nanoscale, there is a fundamental incompatibility between light at the microscale and devices and processes at the nanoscale. Nanostructured metals which support surface plasmon modes can concentrate electromagnetic (EM) fields to a small fraction of a wavelength while enhancing local field strengths by several orders of magnitude. For this reason, plasmonic nanostructures can serve as optical couplers across the nano–micro interface: metal–dielectric and metal–semiconductor nanostructures can act as optical nanoantennae and enhance light matter coupling in nanoscale devices. This book describes how one can fully integrate plasmonic nanostructures into dielectric, semiconductor, and molecular photonic devices, for guiding photons across the nano–micro interface and for detecting molecules with unsurpassed sensitivity. ·Nanophotonics and Nanoplasmonics·Metamaterials and negative-index materials·Plasmon-enhanced sensing and spectroscopy·Imaging and sensing on the nanoscale·Metal Optics

This book was released on 2014-04-22 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the application of Tip-Enhanced Raman spectroscopy (TERS) to non-transparent and non-conductive samples, allowing for the optical characterization of nanoelectronic devices. As such, nano-crystals are analyzed as a model system for the investigation of chemical and structural properties. Furthermore, a novel method for mapping the refractive index of materials with nanometer resolution is presented. The technological progress of electronics through miniaturization has reached the nanoscale while new materials with high performance and functional properties gain importance. Quality control and the scientific understanding of size effects in electronic nanostructures are required more than ever to consolidate existing technologies and to determine scaling limits of new materials. Conventional techniques, including scanning electron and scanning probe microscopy, provide topographic information but only very limited chemical information to analyze the physical properties of nanomaterials. Chemical and structural sensitivity is available by Raman or infrared spectroscopy, but with a spatial resolution limited to the microscale by the diffraction limit of light. TERS combines the virtues of scanning probe microscopy with those of optical spectroscopy to overcome the diffraction limit through the excitation of surface plasmons on a scanning probe tip to confine light to nanometers. In this work, a TERS system was installed to operate on opaque samples by employing optical side access. TERS probes were fabricated by electrochemical etching and operated in scanning tunneling microscopy and atomic force microscopy with quartz tuning forks to enable scanning on various surfaces. TERS was then applied to ferroelectric lead titanate nano-crystals on a platinized silicon substrate as a model system for nanostructured, charge-based memory devices at the onset of finite size effects.
