Paper Abstract

A novel correlator based on 3x3 coupler with dual loops which perform XOR operation and feedback with power compensating is proposed. The validity of device is demonstrated by the simulation with realistic parameters at 10Gb/s and 40Gb/s. For this kind of correlator, the amplified spontaneous emission (ASE) noise accumulation is the crucial limitation. The relationship between the output signal-to-noise ratio (SNR) and bits to be compared is analyzed theoretically. The ASE noise is retrained and the output SNR is enhanced by introducing the assistant light advisably. Therefore, this device can perform the comparison of arbitrary length data. If the dual loops length is minimized by integrate, the devise is applicable for the higher speed data.
