Abstract :
All-optical circuits for packet compression and decompression are proposed for compressing and decompressing differential phase shift keyed (DPSK) packets, using optical delay lines and quantum-dot semiconductor optical amplifier (QDSOA) devices in Mach-Zehnder interferometer (MZI) structures. Packet compression and decompression are simulated between 40 Gb/s and 160 Gb/s and an eye opening penalty (EOP) below 0.4 dB is obtained for packets of size up to 1024 bits. For 64 bit packets, the same packet can be consecutively compressed and decompressed 4 times and an EOP of less than 1 dB is obtained.
