We extend the functionality of our photonic spectral processor to operate over any input polarization state by introducing polarization diversity. Some of the expected and unexpected challenges are discussed, leading to ∼1GHz resolution programmable filtering.
Spectrally dispersed light from a fine resolution waveguide grating router (WGR) of 25-GHz free spectral range that radiates to free space is spatially filtered at ∼1 GHz optical resolution and 50 MHz spectral addressability using a liquid crystal on Silicon (LCoS) spatial light modulator (SLM). Fabrication imperfections leading to phase errors on the 32 waveguide arms of the WGR are corrected using...
A new free-space optics switching solution having internally multiple wavelength-selective switches to which input/output ports can be reconfigurably associated is presented. The switch enables the realization of a colorless/directionless/contentionless ROADM node with flexible channel allocation.
Spectrally dispersed light from a fine resolution AWG is spectrally filtered at ∼1 GHz resolution with an SLM. AWG phase errors were permanently trimmed waveguide-by-waveguide with an excimer laser by inducing stress in the glass.
