This book was released on 1990 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we investigate the optical properties of modulation doped GaAs/AlGaAs and strained-layer undoped InGaAs/GaAs multiple quantum well structures (MQWS). The phenomena studied are the effects of carrier, strain, and the electric field on the absorption of excitons. For GaAs/AlGaAs modulation doped MQWS, the quenching of excitons by free carriers has been demonstrated. The comparison of the experimental results with calculations which consider phase space filling, screening, and exchange interaction showed the phase space filling to be the dominant mechanism responsible for the change of oscillator strength and binding energy of excitons associated with partially filled subband. On the other hand, the screening and exchange interaction are equally important to excitons associated with empty subbands. For InGaAs/GaAs strained-layer MQWS, we have demonstrated that the band edges are dramatically modified by strain. We determined the band discontinuities at InGaAs/GaAs interfaces using optical absorption, and showed that in this structure the heavy holes are confined in InGaAs layers while the light holes are in GaAs layers, in contrast to GaAs/AlGaAs MQWS. We also explore applications of GaAs/AlGaAs and InGaAs/GaAs MQWS to opto-electronic devices. The principle of devices investigated is mainly based on the electric field effect on the excitonic absorption in MQWS (the quantum confined Stark effect). Two examples presented in this thesis are the strained-layer InGaAs/GaAs MQWS electroabsorption modulators grown on GaAs substrates and the GaAs/AlGaAs MQWS reflection modulators grown on Si substrates. The large modulation observed in the absorption coefficient by an electric field is expected to facilitate opto-electronic integration.

This book was released on 2013 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the ever-growing usage of free space optical communication implementations, new innovations are currently being made to help improve the quality of transmission of these systems. One particular method employed to help improve transmission efficiency of optical links is shifting the transmission wavelength into the mid-infrared spectrum. Studies have shown sufficient increase in atmospheric transmission at and around mid-infrared wavelengths (near 3-5 mm). In order to successfully implement such systems at these wavelengths, devices must first be designed that are capable of optical communication operation at such wavelengths. One such device common in modern free space optical systems is the reflective modulator. This device minimizes the pointing and tracking associated with establishing free space optical connections. In this dissertation, a free space optical reflective modulator is designed using Gallium Arsenide and Aluminum Arsenide (GaAs/AlAs) to operate at midinfrared transmission wavelengths. The reflective modulator consists of multiple quantum well modulator (QWM) atop of a distributed Bragg reflector (DBR). The physical device characteristics are analyzed and the device functionality evaluated using optical characterization techniques.

Available in PDF, EPUB and Kindle. Book excerpt: We present new insights into the problem of the isoelectronic nitrogen (N) impurity in gallium arsenide (GaAs). By performing photoluminescence (PL), photoluminescence excitation (PLE), transmission, and time decay measurements through a broad range of pressures, we were able to positively identify and track previously unseen states arising from the N impurity. The first observation we make is of a dramatic increase in luminescence as N forms an isolated state within the gap around 22kbar. We attribute this effect to N acting as a nonradiative trapping center while still resonant with the conduction band states. We also note the appearance, above 22kbar, of a broad band-to-acceptor like emission below the band edge, which we associate with a band to N acceptor transition. The next major observation we report is of the excited state of the N[Subscript x] exciton. We find this state to be clearly identifiable for the pressure range [Difference symbol]25kbar to [Difference symbol]30kbar, and is weak in PL, but shows enormous absorption signals in PLE and transmission. The spacing of this level from N[Subscript x]-B is in good agreement with the established theory of shallow acceptor levels. We then move on to the identification of a second bound state associated with N. This state, designated N[Subscript Gamma symbol], was previously reported for the GaP system and the GaAs[Subscript l-x]P[Subscript x] alloy, but has not, until now, been positively identified in GaAs. We find the state to be degenerate with the shallow donor level for pressures up to [Difference symbol]30kbar. The emission from this state is found to possess unique N characteristics and is seen to move in pressure with both shallow and deep like properties. We conclude with a discussion of the process of lasing in N doped GaAs. We present data consistent with previous studies of the lasing process in GaAs. However, we find an intriguing trend with pressure as we approach the [Gamma]-X crossover. The lasing gain begins to shift in a manner similar to N[Subscript Gamma]. In fact, N[Subscript Gamma] appears to act as an upper bound on the laser emission. We believe this to be preliminary evidence of the influence of N on the lasing mechanism.
