چکیده
An optical receiver for 40 Gbit=s communication systems with 8274 V=W conversion gain and 950 mVp–p limiting differential output is reported. A back-to-back sensitivity of 9.4 dBm at a bit error rate of 10 12 was observed for a 2 1 pseudorandom binary sequence. The receiver incorporates an InP based pin diode, a transimpedance amplifier and a limiting amplifier. This is the largest conversion gain with high sensitivity reported for 40 Gbit=s receivers without optical amplification.

Introduction: An add-drop multiplexer (ADM) is one of the key elements in optical time division multiplexed (OTDM) networks. Various methods of performing OTDM add-drop have been demonstrated. Recently add-drop operation at 16 10 Gbit=s has been demonstrated with the use of a gain transparent ultrafast nonlinear interferometer (GT-UNI) [1] switch and at 4 40 Gbit=s with travelling-wave electroa...

متن کاملAsynchronous Digital Optical Regenerator for 4 x 40 Gbit/s WDM to 160 Gbit/s OTDM Conversion.
We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...
