30 ps chromatic dispersion compensation of 400 fs pulses at 100 Gbits/s in optical fibres using an all fibre photoinduced chirped reflection grating

Pulse recompression and dispersion compensation are demonstrated using 8 mm long all fibre photoinduced chirped reflection gratings at 1560 nm. Optical pulses of 400 fs at 100 Gbits/s are almost fully recompressed after undergoing broadening of approximately 30 ps in an optical fibre; a compression ratio of 67 is achieved.
