Abstract :
A tunable optical heterodyne receiver for a coherent FDM broadcasting system has been developed, using a wavelength tunable local DBR LD and polarization diversity. In the 8 channel FDM experimental system, 114 GHz capture range, 80 GHz lock range and high speed arbitrary channel selection were realized. Also, it was confirmed that there was no crosstalk penalty in the 400 Mb/s FSK FDM system
