Abstract :
The authors estimate the frequency/power measurement error of a multiwavelength simultaneous monitoring circuit. The initial frequency measurement error is dominated by an imbalance in the bandwidths of the adjacent ports, compared with those of the optoelectrical conversion efficiency. The polarisation dependent power monitoring error is estimated to be ±0.18 and ±0.08 dB at the normalised-bandwidths of 0.4 and 0.6, respectively
