Abstract
A wavelength selective switch for selectively switching optical wavelength components of an optical signal uses both LCoS and MEMs switching technologies to improve device performance. Specific performance improvements may include more ports, better spectral performance and isolation, improved dynamic crosstalk, more flexible attenuation options, integrated channel monitoring and compressed switch heights.
