摘要：

A new configuration of all-optical 4-bit parity checker is proposed that incorporates six semiconductor optical amplifiers (SOAs). The proposed 4-bit parity generator is numerically simulated by solving nonlinear coupled equations that explain the cross gain modulation (XGM) effect in individual SOAs. The full design is easy to understand. The outputs can be tested at every step with the help of waveforms. This makes easy error analysis of the circuit. The fault detection and correction can be made comfortably. This design proves that when we reach up to chip level design, the economical circuit is integration capable.
