Experimental verification of noise squeezing by an optical intensity filter in high-speed transmission

R. Ludwig A. Sizmann U. Feiste Colja Schubert M. Kroh

We report on the application of a highly asymmetric nonlinear optical loop mirror (NOLM) for noise reduction and improvement of the system performance in 10-40 Gbit/s transmission experiments. The technique is applicable for bit-rates in excess of 160 Gbit/s.

A Linear Differential Transimpedance Amplifier for 100-Gb/s Integrated Coherent Optical Fiber Receivers

IEEE Transactions on Microwave Theory and Techniques (2017)

A. Awny R. Nagulapalli M. Kroh J. Hoffmann Patrick Runge

This paper presents the design and measurements of a 32-Gb/s differential-input differential-output transimpedance amplifier (TIA) employed in dual polarization integrated coherent receivers for 100-Gb Ethernet. A circuit technique is shown that uses a replica TIA to stabilize the operating point of the two shunt-feedback input stages as well as to cancel the dc part of the two complementary input currents and balances their offset. The TIA can be operated in two modes, an automatic gain control mode to retain a good total harmonic distortion (THD) over a wide dynamic range and a manual gain control mode. Electrical as well as optical-electrical characterization of the TIA are presented. It achieves a maximum differential transimpedance of 74 dB

Design effects on the performance of high-speed Ge photo detectors

Stefan Lischke Woo‐Young Choi Lars Zimmermann D. Knoll Christian Mai

We investigate design effects on the opto-electrical frequency response of waveguide-coupled, lateral Ge p-i-n photodiodes to estimate the sensitivity of this response to diode fabrication tolerances and, in particular, to improve our understanding how diffusion of photo carriers acts on the response behavior.

Hybrid-Integrated Polarization Diverse Coherent Receiver Based on Polymer PLC

IEEE Photonics Technology Letters (2012)

Jin Wang M. Kroh Thomas Richter Abongwa Theurer A. Matiss

A dual-polarization coherent receiver using polymer planar lightwave circuit technology is demonstrated for the first time. It comprises optical 90 hybrids on the basis of polymer waveguides, polarization beam-splitting thin-film elements, and photodetectors made of InGaAsP/InP. The chip size fits into the existing receiver package standards. The receiver assembly shows a high polarization extinction ratio (>;25 dB over C-band) and is successfully operated in system experiments with 16-quadrature-amplitude modulation and quadrature phase-shift keying modulation up to 112 Gb/s.
