Miniaturization of 2-D Wavelength-Hopping Time-Spreading Incoherent Optical CDMA Network by Pulse Carving of CW Laser Source

We have investigated the performance of an incoherent optical code division multiple access network using three distributed feedback laser diodes as the multi-wavelength optical source. The system, operating at 2.488 GHz, has 10^-9 bit error rate measurements with -35 dBm optical power and pseudorandom bit sequence of length 2³¹-1. The distributed feedback laser is a promising alternative optical source to miniaturize the optical code division multiple access system.
