40-Gbit/s 32-bit optical packet compressor/decompressor based on a photonic memory

We propose an optical packet compressor/decompressor with a spectral-width conversion capability using a CMOS memory sandwiched between all-optical serial-to-parallel and photonic parallel-to-serial converters. We demonstrate the 40-to-80-Gbit/s compression and 40-to-10-Gbit/s decompression of 32-bit optical packets.
