Abstract :
We report a multiwavelength simultaneous monitoring method using the integrated planar lightwave circuit and fast Fourier transform techniques with a single detector. Accuracies of wavelength and power measurements are within /spl plusmn/ 3 GHz and /spl plusmn/ 0.5 dB, both in a 13-dB dynamic range of optical power, respectively.
