This paper presents an optical circuit for frame synchronization and pulse compression of 10G Ethernet frames with 12000 bits and multiplexing to a 170 Gbit/s optical timedivision multiplexed data stream.
A silicon waveguide-based ultra-fast optical sampling system is successfully demonstrated using a free-running fiber laser with a carbon nanotube-based mode-locker as the sampling source. A clear eye-diagram of a 320 Gbit/s data signal is obtained.
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.
