Abstract
An athermalized wavelength router comprises a base, a fiber optic input and output component, a routing array having a plurality of reflectors and a routing array/input and output mount that mounts the routing array and the input and output component to the base. The router further includes a grating and a grating mount that mounts the grating to the base. A lens is positioned between the input and output component and the grating. The base, the routing array/input and output mount and the grating mount are configured to maintain a generally constant focal length and a pointing angle onto the routing array as the temperature of the router changes.
