Journal ArticleDOI
74 nm wavelength tuning range of an InGaAsP/InP vertical grating assisted codirectional coupler laser with rear sampled grating reflector
TL;DR: In this article, a vertical grating-assisted codirectional coupler laser with rear sampled grating reflector (GCSR) combines single-mode operation over a very wide tuning range of 74 nm with a side-mode suppression of better than 30 dB over most of the wavelength span.
Journal ArticleDOI
Room-temperature pulsed operation of 1.5-μm vertical cavity lasers with an InP-based Bragg reflector
TL;DR: In this article, a 1.5/spl mu/m vertical-cavity laser that utilizes one GaInAsP-InP and one Si-SiO/sub 2/ mirror was reported.
Journal ArticleDOI
Importance of metalorganic vapor phase epitaxy growth conditions for the fabrication of GaInAsP strained quantum well lasers
TL;DR: In this paper, a distributed feedback (DFB) laser structure employing 8 compressive strained wells with lattice-matched as well as strain-compensating barriers has been grown by low-pressure metalorganic vapor phase epitaxy (LP-MOVPE).
Journal ArticleDOI
Access to 20 evenly distributed wavelengths over 100 nm using only a single current tuning in a four-electrode monolithic semiconductor laser
P.-J. Rigole,Stefan Nilsson,L. Backbom,T. Klinga,J. Wallin,B. Stalnacke,E. Berglind,B. Stoltz +7 more
TL;DR: In this paper, a vertical grating assisted codirectional coupler laser with a super-structure grating distributed Bragg reflector (GCSR) was used to improve tuning regularity.
Journal ArticleDOI
Selective Area Regrowth of Butt-joint Coupled Waveguides in Multi-section DBR Lasers
TL;DR: In this article, the interface between the active layer and the passive waveguide layer in a butt-joint coupled distributed Bragg reflector (DBR) laser in InGaAsP/InP material has been studied.
