Fast Optical Spectrum Estimation Using a Digital Coherent Receiver

We investigate the use of a fast switching DSDBR tunable laser in a coherent receiver to enable microsecond sweeping time over the C-band. Thomson's Multitaper method is used to estimate spectral slices which are then digitally stitched to form the complete scanned spectrum.
