Wavelength selective polarization beam splitter/combiner |
摘要 |
<p>A wavelength selective polarization beam device uses waveguide grating routers (WGRs) having birefringent grating waveguides. When the device is used as a splitter it separates different wavelength channels of a wavelength division multiplexed (WDM) signal as well as the orthogonal polarization components of each wavelength channel. Since the WGR device is reciprocal, it can also be used as a combiner to combine the orthogonal polarization components of each wavelength channel into a WDM signal. <IMAGE></p> |
