Title: WAVELENGTH SELECTIVE SWITCH WITH MONITORING PORTS
Abstract:
Apparatuses and methods for wavelength selective switching and optical performance monitoring are provided. Spatially separated wavelength channels of an optical signal are directed onto an optical deflector array. The optical deflector array is configured so that each wavelength channel is incident on a respective region of the optical deflector array. The optical deflector array is controlled so that, for one or more of the wavelength channels: i) a first portion of the region of the optical deflector array upon which the wavelength channel is incident is configured to steer a first portion of the wavelength channel toward a switching output port; and ii) a second portion of the region is configured to steer a second portion of the wavelength channel toward a monitoring output port.
