A proof-of-concept prototype of optical sub-wavelength switching fabric is demonstrated. The prototype supports petabit switching capacity with agile service granularity and low power consumption.
We propose a novel technique to achieve optical frequency up-conversion in millimeter wave band without any local microwave oscillator. By utilizing injection locking of Febry-Perot Laser diode, a suitable negative dispersion device and polarization interferometer, a 2.5 Gb/s baseband signal is frequency up-conversion to a subcarrier modulation signal at 30.8 GHz.
40 Gb/s optical demultiplexing with amplitude regeneration is demonstrated based on data pump fiber-optical parametric amplification while a 10 GHz short pulse is used as the probe. Four 10 Gb/s output channels with at least 14 dB extinction ratio enhancement and an average 5.5 Q factor is obtained after demultiplexing.
the optical pulses at a multiplied repetition frequency is generated by Fractional Talbot effect in optical fiber. The optical pulses at 20GHz, 40GHz and 50GHz repetition frequency are obtained from the original pulse with 2.8ps width at 10GHz and the optical pulses at 5GHz is octupled to 40GHz.
A simultaneous optical signal extracting and erasing scheme is presented by utilizing four-wave mixing in optical fiber. Two synchronized gate and negation gate pulses, coupled with data stream, produce FWM effect to implement extracting and erasing functions. Experimental results are successfully demonstrated with NRZ data at 10 Gb/s.
A novel approach is proposed to reduce the cross phase modulation between multiple clock pump in the multi-wavelength optical decision based optical fiber parametric amplifier. The dispersive media is used to preprocess the pump clock, and then the clock pump is changed from intensity modulation into phase modulation.
