Abstract
Abstract An optical package particularly suited for use with a pair of optical devices is disclosed. In a preferred embodiment, the package may house an optical transmitting device and an optical receiving device such that the package forms a transceiver. The package advantageously utilizes a number of molded plastic piece parts to reduce the package cost and simplify construction. By utilizing molded components, optical alignment within the package is automatically achieved.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A lightwave communication package comprising a pair of semiconductor optical devices; electrical circuitry disposed on a printed circuit board including a ground plane, and associated with the operation of said pair of semiconductor optical devices; and a lid with an underlying metallic member attached thereto, said metallic member including sidewalls for contacting the printed circuit board ground plane and providing thermal dissipation for the electrical circuitry.
Claim 2
Dependent Claim
66 words
A lightwave communication package comprising a pair of semiconductor optical devices; electrical circuitry disposed on a printed circuit board including a ground plane, and associated with the operation of said pair of semiconductor optical devices; and a lid with an underlying metallic member attached thereto, said metallic member including sidewalls for contacting the printed circuit board ground plane and providing thermal dissipation for the electrical circuitry.
Claim 3
Dependent Claim
