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.
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.
We present the technological merits of combining a high fill factor, one-dimensional, MEMS micro-mirror array for switching and liquid crystal shutters for amplitude control within a wavelength-selective switch (WSS). The combination allows for simplified MEMS actuator design, support for high port counts, high attenuation accuracy, high natural frequency, mechanical robustness against shock &...
