G. A. Keeler, B. E. Nelson, D. Agarwal, and D. A. B. Miller, "Skew and jitter removal using short optical pulses for optical interconnection," IEEE Photonics Technol. Lett. , 12, 714 -716 (2000)

We demonstrate data resynchronization in a multi-channel chip-to-chip free-space optical interconnect for complementary metal-oxide-semiconductor (CMOS) using short optical pulses. Operation of the system is shown at speeds of 82 Mb/s per channel, limited by the repetition rate of teh mode-locked laser used. We show explicitly the ability to resynchronize parallel channels and elimnate timing fluctuations; we remove up to 3/8 of a bit period of interchannel skew and single channel jitter from the transmitted signals in a complete interconnect link that includes optical transmission, reception, and retransmission of digital data.
