Abstract:
A wavelength router, comprising:a base; a fiber optic input and output component; a routing array having a plurality of reflectors; a routing array/input and output mount that mounts the routing array and the input and output component to the base; a grating; a grating mount that mounts the grating to the base at a location spaced apart from the input and output component and the routing array; and at least one lens positioned between the grating and the routing array and between the grating and the input and output component through which signals are transmitted; wherein the base, the routing array/input and output mount and the grating mount are configured to maintain a generally constant distance between the lens and the routing array/input and output mount and to orient the grating relative to the routing array such that signals reflected from the grating are pointed toward the routing array when the temperature of the wavelength router changes.
