Abstract
An improved optoelectronic oscillator scheme for an optical time division multiplexing
(OTDM) system based on cascaded Mach-Zehnder modulator (MZM) and polarization modulator (PolM) is
experimentally investigated. The system can simultaneously realize clock recovery and
demultiplexing. With the MZM working at peak point to generate return-to-zero-33 optical pulses and
the PolM working as an equivalent intensity modulator, a high-quality clock signal with 35-fs timing
jitter is extracted from the 160-GBaud OTDM-differential quaternary phase-shift keying signal.
Narrow short optical switch gates (4 ps) are also generated to demultiplex 160-GBaud signals to
40-GBaud signals. Error-free performance is achieved with 2.4-dB power penalty in the worst case.
