Simultaneous Demultiplexing, Electrical Clock Recovery, and Optical Clock Generation Using Photocurrent and Subharmonic Frequency in a Traveling-wave Electroabsorption Modulator
We demonstrate for the first time using a traveling-wave electroabsorption modulator simultaneously as a photodetector, a demultiplexer, and an optical pulse generator for clock-recovery and demultiplexing at linerates of 40 Gb/s and 160 Gb/s. Introduction Compact optoelectronics components are desired to bring down the cost and ease the maintenance in high capacity optical communication system...
متن کاملGb / s OTDM Networking using Deployed Fiber
We report a 160 Gb/s OTDM network comprising switching and demultiplexing through field deployed fiber. The 160 Gb/s signal was obtained by time-interleaving 16 channels of a 10 Gb/s signal. The add-drop node was realized by using a gain-transparent operation of a semiconductor optical amplifier (SOA). A subharmonic clock recovery with a pre-scaled electro-optical phase locked loop employing an...

We demonstrate an optical clock recovery circuit that extracts the line rate component on a per packet basis from short data packets at 40Gb/s. The circuit comprises a Fabry-Perot filter followed by a novel power limiting configuration, which in turn consists of a 5m highly nonlinear bismuth oxide fiber in cascade with an optical bandpass filter. Both experimental and simulation-based results a...

A multilevel clock and data recovery (CDR) circuit for highspeed serial data transmission was designed using the IBM 6HP 0.25 μm SiGe BiCMOS process technology. The circuit extracts the clock from a 32 Gb/s 4-level pulse amplitude modulated (PAM-4) input signal and outputs four channels of retimed NRZ data at 8 Gb/s per channel. The CDR design incorporates a PAM-4 to 2-bit-binary converter, a p...
