Abstract
Multi-wavelength optical buffer will be a key element in Wavelength Division Multiplexing (WDM) system and all-optical packet-switched networks. In this paper we have presented and demonstrated the dual-wavelength signal buffering in Dual-Loop Optical Buffer (DLOB) based on Semiconductor Optical Amplifier (SOA). The dual-wavelength packets are written in and read out of DLOB by single control signal. As the power of the control signal increasing, the output of the signals is better. In simulation confirmed by experiments, we obtained suitable control power, where the gain and phase-shift difference between "1" bit and "1+1" bit is minimum. More than 12 cycles' buffering results have been obtained and the power loss is lower than 4db.
