Multicasting Characteristics of All-Optical Triode Based on Negative Feedback Optical Amplifiers
We introduce all-optical multicasting characteristics with wavelength conversion based on all-optical triode using two full bands tunable distributed-feedbacklaser diode module at a transfer speed of 10 Gbps to a non-return-zero 231-1 pseudorandom bit sequence system. This multi-wavelength converter device can simultaneously provide two channels of output signal with the support of non-inverted and inverted conversion. We reported an all-optical multicasting wavelength conversion accomplishing cross gain modulation is effective in a semiconductor optical amplifier in order to provide an inverted conversion thus negative feedback. The relationship of received power of back to back signal and output signals with bit error rate was investigated. It was found that the output signal wavelengths were successfully converted and modulated with a power penalty of less than 5 dB. It was realized that all-optical multicasting and wavelength conversion using an optical triode with a negative feedback by two channels at the same time at a speed of 10 Gbps is possible.
