Multiple access techniques are required to meet the demand for high-speed and large-capacity communications in optical networks, which allow multiple users to share the fiber bandwidth. Optical code-division multiple-access (O-CDMA) is receiving increased attention due to its potential applications for local area optical networks. We experimentally investigate an ultrashort pulse O-CDMA scheme based on spectral phase encoding and decoding of coherent mode-locked laser pulses. Strong interference suppression is achieved by using a novel, ultrasensitive nonlinear optical intensity discriminator based on second harmonic generation (SHG) in a periodically-poled lithium niobate (PPLN) waveguide. We have experimentally demonstrated/investigated: (1) 4-user, 2.5 Gb/s and 10 Gb/s O-CDMA system with ultra-low power (aˆ¼30 fJ/bit); (2) reconfigurable all-optical code translation in our O-CDMA testbed; (3) 50 km single mode fiber (SMF) transmission experiments for O-CDMA system; (4) security issues in O-CDMA networks.Multiple access techniques are required to meet the demand for high-speed and large-capacity communications in optical networks, which allow multiple users to share the fiber bandwidth.
