Optic for multi-pass optical channel monitor

A zoned waveplate has a series of transversely stacked birefringent zones alternating with non-birefringent zones. The birefringent and non-birefringent zones are integrally formed upon an AR-coated face of a single substrate by patterning the AR coated face of the substrate with zero-order sub-wavelength form-birefringent gratings configured to have a target retardance. The layer structure of the AR coating is designed to provide the target birefringence in the patterned zones and the reflection suppression.

The first M&#xd7;N WSS may include a first optical element aligned to the monolithic beam steering engine to direct one of the first beams or the second beams relative to the other of the first beams or the second beams, such that the first beams are directed in a different direction from the second beams.
