Abstract

Thermally compensated wavelength division demultiplexers and multiplexers are disclosed. In one aspect, thermally compensated optical systems for use in an optical network are disclosed. The systems include a diffraction grating coupled to a grating mount having a temperature coefficient. The systems further include an optical fiber coupled to a fiber mount having a temperature coefficient and a lens assembly coupled to a lens mount. The lens mount is operable to position the lens assembly between the fiber mount and the grating mount and includes a substantially similar temperature coefficient to the fiber mount.
