Recognition of spectral amplitude codes by frequency swept coherent detection for flexible optial label switching

We propose a new method of recognizing spectral amplitude code by using optical coherent detection with a frequency swept local light source oscillator. Our proposed method offer a substantial simplification in terms of required components to built optical label processing units with enhanced flexibility to accomodate for wavelength tuneability and a large numer of labels. We present a performance analysis, comparison with conventional spectral codes recognition methods, based on computer simulation results. We consider a payload bit rate of 40 Gb/s.
