Monolithic 40-GHz Mode-Locked MQW DBR Lasers for High-Speed Optical Communication Systems
Ronald Kaiser,B. Hüttl +1 more
TL;DR: In this article, the state-of-the-art of the development and fabrication of advanced 1.55mum/40-GHz pulse laser modules with a monolithic InP-based mode-locked distributed Bragg reflector (DBR) MQW chip inside is reported, with respect to the future applications in high-speed optical communications.
Journal ArticleDOI
40 GHz Mode-Locked Semiconductor Lasers: Theory, Simulations and Experiment
TL;DR: In this article, the authors study both theoretically and experimentally typical operation regimes of 40 GHz monolithic mode-locked lasers and derive and apply a simplified Delay-Differential-Equation model which guides them to a qualitative analysis of bifurcations responsible for the appearance and the breakup of different mode-locking regimes.
Journal ArticleDOI
Optical microwave generation and transmission experiments in the 12- and 60-GHz region for wireless communications
Ralf-Peter Braun,G. Grosskopf,Helmut Heidrich,C. von Helmolt,Ronald Kaiser,K. Kruger,U. Kruger,D. Rohde,F. Schmidt,R. Stenzel,D. Trommer +10 more
TL;DR: In this article, a monolithically integrated tunable optical-signal source was developed and used for generating the millimeter-wave signals, which promises a high cost-saving potential for applications in radio-over-fiber systems.
Journal ArticleDOI
100 GBd Intensity Modulation and Direct Detection With an InP-Based Monolithic DFB Laser Mach–Zehnder Modulator
Sophie Lange,Stefan Wolf,J. Lutz,Lars Altenhain,Rolf Schmid,Ronald Kaiser,Martin Schell,Christian Koos,Sebastian Randel +8 more
TL;DR: In this paper, the authors demonstrate 100 GBd operation of an optical transmitter module including a distributed feedback laser monolithically integrated with a Mach-Zehnder modulator (DFB-MZM), to the best of their knowledge for the first time.
Journal ArticleDOI
Waveguide-integrated pin photodiode on InP
TL;DR: An InGaAs PIN photodiode was vertically integrated with an inverted optical rib waveguide in this article, achieving a responsivity of 0.81 A/W at 1.3?m wave-length.
