Journal ArticleDOI
Dynamic, polarization, and transverse mode characteristics of vertical cavity surface emitting lasers
TL;DR: In this paper, the dynamic, polarization, and transverse mode characteristics of InGaAs-GaAs quantum well vertical cavity surface emitting lasers (VCSELs) emitting at 0.98 mu m are investigated.
Journal ArticleDOI
Multiple wavelength tunable surface-emitting laser arrays
Connie J. Chang-Hasnain,J. P. Harbison,Chung-En Zah,M.W. Maeda,L. T. Florez,N. G. Stoffel,T.-P. Lee +6 more
TL;DR: In this article, the authors obtained 140 unique, uniformly separated, single-mode wavelength emissions from a 7*20 VCSEL array and obtained a large total wavelength span (approximately 430 AA) and small wavelength separation (approximately 3 AA) with uncompromised laser performance.
Journal ArticleDOI
Transverse mode characteristics of vertical cavity surface-emitting lasers
Connie J. Chang-Hasnain,Meir Orenstein,A. Von Lehmen,L. T. Florez,J. P. Harbison,N. G. Stoffel +5 more
TL;DR: In this paper, the transverse mode characteristics of vertical cavity surface-emitting (VC-SE) lasers are investigated as a function of transverse dimension for proton-implanted gain-guided VC-SE lasers.
Journal ArticleDOI
Two‐dimensional phase‐locked arrays of vertical‐cavity semiconductor lasers by mirror reflectivity modulation
TL;DR: In this article, the top metal layer of a stained-layer InGaAs quantum well VCSEL structure was patterned laterally by depositing various metals with different optical reflectivities.
Journal ArticleDOI
Vertically stacked multiple‐quantum‐wire semiconductor diode lasers
TL;DR: In this paper, the structure and lasing characteristics of GaAs/AlGaAs vertically stacked multiple-quantum-wire (QWR) semiconductor lasers grown by organometallic chemical vapor deposition on V-grooved substrates are reported.
