Package for optical components
An inexpensive TO- or MO-series package is used to house an optical device, such as a laser, by forming an opening in a side of a package, providing an optical fiber within the opening, and coupling the optical device to the fiber. The package is preferably a TO-258 or some other similar metal package.
