摘要：first a simple all-optical logic device, called Mach Zhender Inferometer is composed by using a Semiconductor Optical Amplifier (SOA) and an optical coupler. This device is used for generating the logical functions (AND, XOR) and a multiplexer and an Encoder is obtained using this device in Optical Tree Architecture. The simulation of Encoder and Multiplexer is done at a rate of 10 Gbit/s and both are simulated for different input logical combinations. Simulations indicate that the device is suitable to operate at much higher bit rate and also for different logical entities. Many lower-speed data streams can be multiplexed into one high-speed stream by means of Optical time division multiplexing (OTDM), such that each input channel transmits its data in an assigned time slot. The assignment is performed by a fast multiplexer switch (mux).The routing of different data streams at the end of the TDM link is performed by a demultiplexer switch (demux) and this demultiplexer is employed using MZI switch as it consists a semiconductor optical amplifier (SOA) and a optical coupler. In this chapter four channel OTDM is simulated at 40 Gbit/s and further it is investigated the impact of the signal power, pulse width and control signal power on BER.
