COHERENT RECEIVER HAVING AN INTERLEAVE-CHIRPED ARRAYED WAVEGUIDE GRATING |
摘要 |
<p>An optical coherent detector that employs an interleave-chirped arrayed waveguide grating (AWG). The AWG has a periodic chirp pattern that enables the AWG to function as an optical 90-degree hybrid. If the AWG is implemented using a birefringent material, then the AWG can also function as a polarization demultiplexer. In one embodiment, the AWG is designed to simultaneously function as a wavelength demultiplexer, a polarization demultiplexer for each wavelength-division- multiplexed (WDM) signal component, and a 90-degree hybrid for each polarization- division-multiplexed component of each WDM signal component.</p> |
