All-Optical Clock Recovery Using Multi-Section Distributed-Feedback Lasers
Recovering the frequency of incoming data sequences in optical transmission lines is important for signal processing. It has been suggested to use all-optical devices, for instance lasers diodes, for this purpose. Recently, self-pulsations have experimentally been discovered in multi-section distributed-feedback lasers. If a self-pulsating laser is exposed to an external data signal, it is expe...
متن کاملAll - Optical Clock Recovery Using Multi - SectionDistributed - Feedback
Recovering the frequency of an incoming data stream in optical transmission lines is important for signal processing. It has been suggested to use all-optical devices, for instance lasers diodes, for this purpose. If a self-pulsating laser is exposed to an external data signal, it is expected that the frequency of the self-pulsation locks to the frequency of the data signal, and clock recovery ...
متن کاملCompact all-optical packet clock and data recovery circuit using generic integrated MZI switches.
We present and evaluate a compact, all-optical Clock and Data Recovery (CDR) circuit based on integrated Mach Zehnder interferometric switches. Successful operation for short packet-mode traffic of variable length and phase alignment is demonstrated. The acquired clock signal rises within 2 bits and decays within 15 bits, irrespective of packet length and phase. Error-free operation is demonstr...
متن کاملAll-optical clock recovery using erbium-doped fiber ring laser incorporating an electro-absorption modulator and a linear optical amplifier
We demonstrated 10-GHz all-optical clock recovery using an erbium-doped fiber laser incorporating an electro-absorption modulator and linear optical amplifier. Stable clock pulses with peak power of 200 mW and pulsewidth of 6 ps are obtained.
متن کاملMultiwavelength optical fibre source
In this paper we described a structure of an original multiwavelength optical fiber source for DWDM systems. In order to obtain a several dozen of optical carriers with highly stable channel spacing of 4.5GHz a single laser source and acousto optic frequency shifter were used. Results of the analysis of the structure properties were presented. Key-Words: DWDM, EDFA, multiwavelength
