100-Gbit/s PDM-QPSK Coherent Receiver with Wide Dynamic Range and Excellent Common-mode Rejection Ratio
Koichi Murata1, Takashi Saida1, Kimikazu Sano1, Ikuo Ogawa1, Hiroyuki Fukuyama1, Ryoichi Kasahara1, Yoshifumi Muramoto1, Hideyuki Nosaka1, Satoshi Tsunashima1, Takayuki Mizuno1, Hiromasa Tanobe1, Kuninori Hattori1, Toshihide Yoshimatsu1, Hiroto Kawakami2, Eiji Yoshida2; 1NTT Photonics Labs., NTT, Japan; 2NTT Network Innovation Labs., NTT, Japan.
We report the design and fabrication of a hybrid-integration-type coherent receiver. We optimize the receiver building blocks, and achieve a -25-dB common-mode rejection ratio and a 20-dB signal input power dynamic range.

Coherent Receiver for 100G Ethernet Applications Based on Polymer Planar Lightwave Circuit
Marcel Kroh1, Jin Wang2, Abongwa Theurer1, Crispin Zawadzki2, Detlef Schmidt2, Reinhold Ludwig2, Mattias Lauermann2, Andreas Beling1, Andreas Matiss1, Colja Schubert2, Andreas Steffan1, Norbert Keil2, Norbert Grote2; 1u2t photonics AG, Germany; 2Fraunhofer Heinrich Hertz Institute, Germany.
A novel dual-quadrature coherent receiver based on a polymer planar lightwave circuit is presented. The packaged receiver is successfully operated in 112 Gb/s DP-QPSK transmission experiments showing only 1.3 dB penalty compared to theory.

Fully passive Si-photonic 90° hybrid for coherent receiver applications
Karsten Voigt1, Lars Zimmermann1,2, Georg Winzer1, Hui Tian2, Bernd Tillack1,2, Klaus Petermann1; 1TU-Berlin, Joint Lab Silicon Photonics, Germany; 2IHP Microelectronics GmbH, Germany.
We present a fully passive Silicon nanowire based optical 90° hybrid based on a 4×4 MMI coupler for application in coherent receivers. The hybrid shows an excess loss <0.5dB and phase accuracy better than 5°.

Temperature Insensitive and Ultra Wideband Silica-based Dual Polarization Optical Hybrid for Coherent Receiver with Highly Symmetrical Interferometer Design
Yusuke Nasu1, Takayuki Mizuno1, Ryoichi Kasahara1, Takashi Saida1; 1Photonics laboratories, NTT, Japan.
We designed temperature-insensitive dual-polarization optical hybrids for the coherent receivers, and firstly demonstrated temperature-insensitive performance with a polarization extinction ratio over 25 dB and phase errors within 3 degrees over fully C- and L-bands.

Photodiode with 0.75 W RF Output Power at 15 GHz
Zhi Li1, Yang Fu1, Huapu Pan1,2, Andreas Beling1, Joe Campbell1; 1Electrical and Computer Engineering, University of Virginia, USA; 2Watson Research Center, IBM, USA.
We demonstrate a flip-chip bonded modified uni-traveling carrier (MUTC) photodiode with a record-high RF output power of 0.75 W at 15 GHz and OIP3 up to 59 dBm. The photodiode has responsivity of 0.7 A/W, 3 dB-bandwidth > 15 GHz and saturation photocurrent > 180 mA at 11 V reverse bias.

A 1 W Linear High-Power InP Balanced Uni-Traveling Carrier Photodetector
Vincent E. Houtsma1, Ting Hu1, Nils Weimann1, Rose Kopf1, Alaric Tate1, John Frackoviak1, Roberto Reyes1, Young-Kai Chen1, Liming Zhang1; 1Alcatel-Lucent, Bell Labs, USA.
We demonstrated a high-power balanced photo-detector with over 1 W of RF output power at 2 GHz and OIP3 of 48 dBm at room temperature. Responsivity is 0.65 A/W and CMRR> 40 dB.
