1. Mitigation of signal distortion in 42.7 Gb/s duobinary transmission using a single chip optical equalizer

Author

Vitaly Mikhailov, Polina Bayvel, Christopher Richard Doerr, Lawrence L. Buhl, and Robert I. Killey

Subjects
Single chip, Transmission (telecommunications), Computer science, Distortion, Electronic engineering, Equalizer, Signal
Abstract

We experimentally investigated the ability of optical equalizers to mitigate signal distortion caused by chromatic dispersion, intrachannel fiber nonlinearities and cascaded filters in 42.7 Gb/s duobinary transmission.

Abstract

We demonstrate operation of a compact chirp managed laser under return-to-zero modulation resulting in an alternate mark inversion format. Single-channel transmission over 8000 km of standard single mode fibre is achieved without any penalty. (2 pages)

4. A single-chip optical equalizer enabling 107-Gb/s optical non-return-to-zero signal generation

Author

A. Wong-Foy, M. Duelk, Christopher Richard Doerr, Evans Yifan Chen, Mark Cappuzzo, G. Raybon, Peter J. Winzer, Lawrence L. Buhl, and L.T. Gomez

Subjects
Physics, Optical cross-connect, Optical transistor, Bandwidth (signal processing), Electronic engineering, Adaptive equalizer, Optical performance monitoring, Optical modulation amplitude, Non-return-to-zero, Optical communications repeater
Abstract

We demonstrate a single-chip optical equalizer that overcomes modulator bandwidth limitations in the first reported 107-Gb/s electrically time-division multiplexed non-return-to-zero transmitter. A high sensitivity of 21-dB optical signal-to-noise ratio at 10-3 bit-error ratio was achieved. (2 pages)
