LCoS Phase Modulator for WSS & OCS
Fast, low-loss phase modulator for wavelength selective switches and optical circuit switches.
Gen 1 · SCOS2KPMG101 (2K) · 4K version

Our Gen 1 liquid-crystal-on-silicon phase modulator reaches full phase depth across the S, C and L bands with a much thinner liquid-crystal layer than standard LCoS. The result is faster switching, lower crosstalk and better efficiency at large steering angles, in the standard form factor and interface, so it can drop into existing WSS optics.
