We propose and experimentally validate a compact and flexible structure of optical signal processing employing a polarization-dependent phase modulator (PM) based optoelectronic oscillator (OEO). The key point of the proposed design is to make good use of the polarization-dependent feature of the LiNbO3 crystal of the PM to realize special phase modulation to intensity modulation conversion. The phase...
One 160 Gb/s optical time division demultiplexer based on two cascaded electro-absorption modulators as sampling windows was demonstrated and experimentally studied in detail. The two stages were used for the 160 Gb/s into 40 Gb/s demultiplexing and 40 Gb/s into 10 Gb/s demultiplexing respectively.
A novel but simply implemented clock recovery for 80Gb/s OTDM signals based on Stimulated Brillouin scattering is presented and demonstrated experimentally. According to the unequal-amplitude even-multiplexed OTDM signals, the frame clock is extracted. In addition, the clock with multiple tributary rates is recovered in simulation utilizing the clock recovery module.
