Optical switching device

摘要

An optical switching device including an optical switching engine may be packaged by omitting an optical bench and disposing optical elements directly on a base of a housing of the optical switching device. The optical switching engine may be disposed on a ceramic portion of the base, and thermally matched to the ceramic base. The base may be reinforced by the housing walls and optional internal rigidity ribs. The optical elements may be thermally matched to the base, and the lid may be strain relieved by thinning lid edges. The housing may be mounted to an external chassis using soft grummets.

主权项

1. An optical switching device comprising:
at least one input port for inputting an optical signal comprising a plurality of wavelength channels; at least one output port for outputting at least one of the wavelength channels; optics for dispersing and redirecting the wavelength channels between the input and output ports; a switching engine optically coupled with the optics for redirecting at least one of the wavelength channels towards a selected output port; and a housing comprising:
a base comprising a first portion comprised of ceramic CTE matched to the switching engine to within 4 ppm/° C., wherein the switching engine is mounted directly to the ceramic first portion; anda cover, the cover and the base enclosing and sealing the optics and the switching engine, wherein the cover is mounted directly to the base for stiffening the base;wherein the optics are CTE matched to the base to within 4 ppm/° C. and mounted directly to the base.
