This paper analyzes in detail the SNR deterioration induced by SLALOM demultiplexer. The slight asymmetry of the coupler will seriously reduce the output SNR. With some pulse delay, the signal-to-clock time delay of a little less than the delay can result in the maximized SNR. Furthermore, increasing pulse delay will degrade the optimal SNR. The optimized configuration of the device is further discussed. It is more suitable to choose the SLA with long carrier lifetime. The optimal time delay between signal and control pulses should be precisely set to be near the control pulsewidth. The SLA can be arbitrarily positioned around any one of a number of periodic sites that equal to the integral times of the control pulse. Through adjusting the optical delay line, SLA’s optical offset to that site should be a little bit less than the control pulsewidth.
