Abstract
Described herein is an optical channel monitor (), including a plurality of input ports in the form of optical fibers () disposed in a vertical 'port displacement' dimension. Each fiber () inputs a respective optical beam () having a plurality of individual wavelength channels. A lens () collimates each beam and converges the beams in the port displacement dimension to a focal plane (). The collimated and converged beams are incident onto a rotatable micro-electromechanical system (MEMS) mirror (), which selectively directs each optical beam onto a wavelength dispersion element in the form of a grism () at a predetermined angle (denoted by φ) in a horizontal 'dispersion' plane. The grism () spatially separates, in the dispersion plane, the wavelength channels contained within each optical beam () by diffraction. The angle at which each channel is diffracted is controlled by the angle φ.
