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: 14
Claim 1
Independent Claim 85 words
A lightwave communication package for use with a pair of semiconductor optical devices, CHARACTERISED IN THAT the package comprises a plastic frame housing (e.g.12) including a first cavity (e.g.14) and a second cavity (e.g.28); an electronic subassembly (e.g.16) for attachment to the plastic frame housing within the first cavity such that electrical leads (e.g.18) from the electronic subassembly extend therethrough; and a plastic receptacle (e.g.26) for holding the pair of optical devices, the receptacle being attached to the plastic frame housing within the second cavity.
Claim 2
Dependent Claim 39 words
A lightwave communication package as defined in claim 1 wherein the plastic frame housing includes a plurality of features (e.g.11) surrounding the first cavity on the interior walls thereof to secure the electronic subassembly within said plastic frame housing.
Claim 3
Dependent Claim 24 words
A lightwave communication package as defined in claim 1 wherein the plastic receptacle is attached to the plastic frame housing utilizing ultrasonic bonding techniques.
Claim 4
Dependent Claim 26 words
A lightwave communication package as defined in claim 1 wherein the plastic receptacle is formed to hold a transmitter semiconductor device and a receiver optical device.
Claim 5
Dependent Claim 76 words
A lightwave communication package for use with a pair of semiconductor optical devices, said package including a receptacle (e.g.26) for holding a pair of optical subassemblies housing said optical devices CHARACTERISED IN THAT the receptacle is formed of a plastic material capable of providing automatic alignment between said pair of optical devices and optical fibers attached thereto, said receptacle comprising a plurality of electrical power pins (e.g.25) molded within to provide electrical power to exterior components.
Claim 6
Dependent Claim 31 words
A lightwave communication package as defined in claim 5 wherein the plastic receptacle further comprises a metallic spring member (e.g.27) for securing the pair of optical subassemblies within said plastic receptacle.
Claim 7
Dependent Claim 51 words
A lightwave communication plastic package for housing a pair of semiconductor optical devices and the electrical circuitry associated therewith, CHARACTERISED IN THAT the package further comprises a lid with an underlying metallic member (e.g.34) attached thereto, said metallic member including sidewalls (e.g.35) for contacting the electrical circuitry and providing thermal dissipation.
Claim 8
Dependent Claim 26 words
A lightwave communication package as defined in claim 7 wherein the sidewalls include flanged end portions (e.g.33) to facilitate connection of the lid to the package.
Claim 9
Dependent Claim 34 words
A lightwave communication package as defined in claim 7 wherein the metallic member includes a central partition (e.g.36) for physically isolating the electrical circuitry associated with separate ones of the pair of optical devices.
Claim 10
Dependent Claim 16 words
A lightwave communication package as defined in claim 7 wherein the lid comprises a plastic material.
Claim 11
Dependent Claim 22 words
A lightwave communication package as defined in claim 1, 5 or 10, wherein the housing and/or receptacle comprises a high-performance engineering plastic.
Claim 12
Dependent Claim 14 words
A lightwave communication package as defined in claim 7 wherein the lid is metallic.
Claim 13
Dependent Claim 21 words
A lightwave communication package as defined in claim 7 wherein the lid and metallic member are formed as a single unit.
Claim 14
Dependent Claim 22 words
A lightwave communication package as defined in claim 10 wherein ultrasonic bonding is used to attach the lid to the plastic package.
