Journal ArticleDOI
Damping-limited modulation bandwidths up to 40 GHz in undoped short-cavity In/sub 0.35/Ga/sub 0.65/As-GaAs multiple-quantum-well lasers
S. Weisser,Eric C. Larkins,K. Czotscher,W. Benz,J. Daleiden,Ignacio Esquivias,J. Fleissner,John D. Ralston,Beatriz Romero,R.E. Sah,A. Schonfelder,J. Rosenzweig +11 more
TL;DR: In this article, the authors demonstrate record direct modulation bandwidths from MBE-grown Insub 035/Ga/sub 065/As-GaAs multiple-quantum-well lasers with undoped active regions and with the upper and lower cladding layers grown at different growth temperatures.
Journal ArticleDOI
Uncooled high-temperature (130/spl deg/C) operation of InGaAs-GaAs multiple quantum-well lasers at 20 Gb/s
K. Czotscher,Eric C. Larkins,S. Weisser,W. Benz,J. Daleiden,J. Fleissner,M. Maier,John D. Ralston,J. Rosenzweig +8 more
TL;DR: In this paper, the Fabry-Perot high-speed short-cavity InGaAs-GaAs multiple-quantum-well laser operating at 1.1-/spl mu/m wavelength was described.
Journal ArticleDOI
Chemical analysis of a Cl2/BCl3/IBr3 chemically assisted ion‐beam etching process for GaAs and InP laser‐mirror fabrication under cryo‐pumped ultrahigh vacuum conditions
TL;DR: In this paper, the compatibility of Cl2/BCl3/IBr3 etch gas mixtures with a cryo-pumped ultrahigh vacuum chemically assisted ion-beam etching system was investigated.
Proceedings ArticleDOI
37 GHz direct modulation bandwidth in short-cavity InGaAs/GaAs MQW lasers with C-doped active regions
S. Weisser,Eric C. Larkins,Konrad Czotscher,W. Benz,J. Daleiden,J. Fleissner,M. Maier,John D. Ralston,Beatriz Romero,A. Schonfelder,J. Rosenzweig +10 more
TL;DR: In this article, the InGaAs/GaAs MQW laser with a similar epilayer structure, but with the Be-doping in the core replaced by carbon (C), resulting in a modulation-doped core region.
Journal ArticleDOI
Sidewall slope control of chemically assisted ion-beam etched structures in InP-based materials
J. Daleiden,K. Czotscher,C. Hoffmann,Rudolf Kiefer,S. Klussmann,Stefan Müller,A. Nutsch,W. Pletschen,S. Weisser,Günther Tränkle,Juergen Braunstein,G. Weimann +11 more
TL;DR: In this article, a chemical assisted ion beam etching (CAIBE) of InP-based materials has been developed with BCl3/Ar in comparison to Cl2/Ar and IBr3/AR.
