We experimentally demonstrate a 160-Gb/s Ethernet packet switch using an 8.6-mm-long silicon nanowire for optical burst switching, based on cross phase modulation in silicon. One of the four packets at the bit rate of 160 Gb/s is switched by an optical control signal using a silicon based $1\times 1$ all-optical packet switch. Error free performance (BER < 1E-9) is achieved for the switched packet...
We demonstrate simultaneous regeneration of 4×160-Gbit/s signals in a HNLF. The receiver powers at the BER of 10-9 are improved by 1.9 dB, 1.8 dB, 1.6 dB and 1.5 dB for the four channels, respectively.
It is shown how introducing a limited rise time to the driving signal enables all-optical clock recovery of NRZ-DPSK signals generated using a phase modulator. A Fabry-Perot filter is used to generate the optical clock.
High repetition rate stable short pulse sources play an important role in high speed optical communication systems. Besides developing a short pulse laser with very high fundamental repetition rate, the high repetition rate pulse train can also be obtained using various optical multiplication techniques, based on a Fabry-Perot filter or a fiber Bragg grating. A more stable system may be achievable...
We demonstrate a silicon-on-insulator microring resonator with a free-spectral-range of 0.32 nm, an extinction ratio of 27 dB, and a quality factor of ~140900 at 1550 nm that is used for pulse repetition-rate multiplication from 10 to 40 GHz.
