Abstract
An optical package is provide including a housing having first and second ends. A ferrule receiving bore is formed in the first end, and an optics cavity is formed in the second end. The optics cavity and the ferrule receiving bore are axially aligned with one another along an optical axis defined by the package. A mounting cap is inserted over the optics cavity and frictionally engages an outer surface of the housing. The end cap includes an endplate and a substrate having an optical device mounted thereon. The sleeve, focusing element and a mounting ring may be insert molded within the housing.
Claims27
An optical package comprising:
- a housing having a first end and a second end, a ferrule receiving bore being formed in the first end and an optics cavity formed in the second end, axially aligned with the ferrule receiving bore;
- a sleeve insert molded within the ferrule receiving bore adjacent the first end;
- a focusing element insert molded within the housing adjacent the ferrule receiving bore;
- and
- a mounting ring insert molded at the second end of the housing adjacent the optics cavity.
An optical package for transferring single mode propagation comprising:
- a plastic housing having a first end and a second end, a ferrule receiving bore being formed in the first end and an optics cavity formed in the second end, axially aligned with the ferrule receiving bore;
- and
- a ceramic sleeve mounted within the ferrule receiving bore wherein the housing forms a lip around a first end of the ceramic sleeve and a cup around a second end of the ceramic sleeve in order to retain the ceramic sleeve therein.
A method of forming optical package assembly comprising the steps of:
- forming a transfer mold having areas for receiving a sleeve, a focusing element and a mounting ring;
- and
- injection molding a polymer material into the transfer mold and around the sleeve focusing element and mounting ring in order to form an optical package housing assembly.
An optical package comprising:
- a plastic housing having a first end and a second end, a ferrule receiving bore being formed in the first end and an optics cavity formed in the second end, axially aligned with the ferrule receiving bore;
- and
- a metallic mounting ring insert molded within the housing at the second end.
