Book excerpt: The huge progress which has been achieved in the field is covered here, in the first comprehensive monograph on vertical-cavity surface-emitting lasers (VCSELs) since eight years. Apart from chapters reviewing the research field and the laser fundamentals, there are comprehensive updates on red and blue emitting VCSELs, telecommunication VCSELs, optical transceivers, and parallel-optical links for computer interconnects. Entirely new contributions are made to the fields of vectorial three-dimensional optical modeling, single-mode VCSELs, polarization control, polarization dynamics, very-high-speed design, high-power emission, use of high-contrast gratings, GaInNAsSb long-wavelength VCSELs, optical video links, VCSELs for optical mice and sensing, as well as VCSEL-based laser printing. The book appeals to researchers, optical engineers and graduate students.

Download or read book Nonlinear Laser Dynamics written by Kathy Lüdge and published by John Wiley & Sons. This book was released on 2012-04-09 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: A distinctive discussion of the nonlinear dynamical phenomena of semiconductor lasers. The book combines recent results of quantum dot laser modeling with mathematical details and an analytic understanding of nonlinear phenomena in semiconductor lasers and points out possible applications of lasers in cryptography and chaos control. This interdisciplinary approach makes it a unique and powerful source of knowledge for anyone intending to contribute to this field of research. By presenting both experimental and theoretical results, the distinguished authors consider solitary lasers with nano-structured material, as well as integrated devices with complex feedback sections. In so doing, they address such topics as the bifurcation theory of systems with time delay, analysis of chaotic dynamics, and the modeling of quantum transport. They also address chaos-based cryptography as an example of the technical application of highly nonlinear laser systems.

This book was released on 2003-09-04 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: A practical, hands-on guidebook for the efficient modeling of VCSELs Vertical Cavity Surface Emitting Lasers (VCSELs) are a unique type of semiconductor laser whose optical output is vertically emitted from the surface as opposed to conventional edge-emitting semiconductor lasers. Complex in design and expensive to produce, VCSELs nevertheless represent an already widely used laser technology that promises to have even more significant applications in the future. Although the research has accelerated, there have been relatively few books written on this important topic. Analysis and Design of Vertical Cavity Surface Emitting Lasers seeks to encapsulate this growing body of knowledge into a single, comprehensive reference that will be of equal value for both professionals and academics in the field. The author, a recognized expert in the field of VCSELs, attempts to clarify often conflicting assumptions in order to help readers achieve the simplest and most efficient VCSEL models for any given problem. Highlights of the text include: * A clear and comprehensive theoretical treatment of VCSELs * Detailed derivations for understanding the operational principles of VCSELs * Mathematical models for the investigation of electrical, optical, and thermal properties of VCSELs * Case studies on the mathematical modeling of VCSELs and the implementation of simulation programs

Book excerpt: Le laser à cavité verticale émettant par la surface (VCSEL ou Vertical-Cavity Surface-Emitting Laser) comporte des avantages compétitifs par rapport aux lasers émettant par le côté. Le VCSEL présente souvent deux modes de polarisation linéaire orthogonaux avec des fréquences et des gains optiques presque identiques. Dès lors, de faibles perturbations telles que des modifications du courant d injection ou de la température peuvent induire des basculements de polarisation. Toutefois, en utilisant un schéma d injection optique d un faisceau laser externe, il est possible de contrôler ces instabilités de polarisation. Nous nous intéressons au contrôle du basculement de polarisation, à la bistabilité de polarisation ainsi qu à la compétition des modes transverses d un VCSEL soumis à injection optique de polarisation orthogonale. En variant les paramètres d injection¡(puissance injectée et désaccord en fréquence entre le laser maître et le VCSEL), nous montrons que le basculement de polarisation implique des dynamiques non linéaires telles le mélange d ondes, le cycle limite, la résonance subharmonique ainsi qu une route de doublement de période vers le chaos optique. L analyse des bifurcations sous-jacentes permet de dresser une cartographie des dynamiques de basculement de polarisation du VCSEL. orthogonaux affecte la qualité de la synchronisation du chaos. Ces résultats sont intéressants dans le cadre du développement de liaisons de communication sécurisée par chaos optique. Dans notre thèse, nous étudions également la synchronisation du chaos de VCSELs dans un schéma de couplage unidirectionnel. Nous montrons que la compétition des modes de polarisation linéaire.

Download or read book Polarization Mode Control of Long-wavelength VCSELs by Intracavity Patterning written by and published by . This book was released on 2016 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polarization mode control is enhanced in wafer-fused vertical-cavity surface-emitting lasers emitting at 1310 nm wavelength by etching two symmetrically arranged arcs above the gain structure within the laser cavity. The intracavity patterning introduces birefringence and dichroism, which discriminates between the two polarization states of the fundamental transverse modes. We find that the cavity modifications define the polarization angle at threshold with respect to the crystal axes, and increase the gain anisotropy and birefringence on average, leading to an increase in the polarization switching current. As a result, experimental measurements are explained using the spin-flip model of VCSEL polarization dynamics.

Download or read book Polarization switching, locking and synchronization in VCESLs with optical injection written by Ignace Gatare Gahangara and published by . This book was released on 2008 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vertical-cavity surface-emitting lasers (VCSELs) have competitive advantages with respect to conventional edge-emitting lasers such as the fabrication of dense two-dimensional VCSEL arrays for optical interconnects. VCSELs exhibit intriguing polarization properties which are critical in polarization-sensitive applications. Polarization switching (PS) between two VCSEL's preferential orthogonal linearly polarized (LP) modes may be induced by changing the bias current, temperature or, externally, through orthogonally polarized optical injection. Depending on optical injection parameters, i.e., the injected power and the frequency detuning, injection-locking of the VCSEL can be achieved. We contribute to the study of polarization bistability, polarization switching (PS), injection-locking and transverse mode competition in a VCSEL subject to orthogonal continuous-wave optical injection. We experimentally show and theoretically demonstrate that PS and locking may involve rich nonlinear dynamics including wave mixing, limit cycle, subharmonic resonances or a period-doubling route to chaos. In particular, we analyze the interplay between PS and the underlying nonlinear dynamics, and unveil its bifurcation mechanisms. Our study brings a new insight into the physics of polarization dynamics in externally-driven VCSELs. Chaos synchronization of coupled VCSELs is also investigated. A feedback-induced chaotic light from the master VCSEL is unidirectionally injected into the slave VCSEL. We show that the synchronization quality can be significantly enhanced when chaos involves both orthogonal LP modes. This result is interesting for chaos communication schemes based on VCSELs.
