This book was released on 1993 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is divided into three Sections: the first covering the work done in the area of high speed InGaAs/GaAs strained quantum well lasers; the second in the material growth and laser fabrication in the InGaAs/AlInGaAs system; and the third in the Gas Source Molecular Beam Epitaxy (GSMBE) of In materials. This contract began at a time when quantum well laser bandwidths were severely limited for unknown reasons and the largest bandwidths were in bulk lasers. This has all changed now. Strained quantum well lasers were fabricated during the initial phase of this program resulting in anomalously large damping rates in quantum well lasers. Large damping rates result in small bandwidth because the lasers become critically damped at a low frequency. During the second portion of the contract, a theory describing the reasons for the resonance frequency, damping frequency, K factor, intensity noise, internal efficiency injection efficiency and wavelength chirping has been derived. Theoretical and experimental evidence in this program shows that carrier transport can lead to significant low frequency parasitic-like, rolloff that reduces the modulation response by as much as a factor of six in quantum well lasers.

Download or read book Advanced Technology for Improved Quantum Device Properties Using Highly Strained Materials written by W. J. Schaff and published by . This book was released on 1989 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strained layer GaInAs/GaAs heterostructures for improved high frequency high performance as a result of strained modified valence band structure have been investigated. A new laser structures has been successfully developed which permits direct high frequency modulation of non wire-bonded lasers. The first demonstration of improved microwave frequency bandwidths for lasers has been achieved. Substantial improvement in bandwidth for strained GaInAs quantum well graded index separate confinement heterostructure lasers over unstrained GaAs quantum well lasers has been measured, accompanied by a reduction in threshold current densities for lasing. Strained P-channel MODFETs have been fabricated, but show no significant improvement in high frequency performance. Fundamental materials properties of strained layer GaInAs quantum wells are being investigated and theoretical examination of the properties of strained layer quantum wells are being conducted. Keywords: Quantum chemistry, Lasers, Laser materials. (CP).
