Abstract
An optoelectronics packaging assembly is provided having a ceramic base on which is connected an optoelectronics device. The optoelectronic device is maintained in an enclosure formed by a housing, the base and/or other structures. The packaging assembly includes means for placing the base and the optoelectronics device in electrical communication with an external component, for example, a printed circuit board. The means include solder balls, J-shaped leads, bent leads, and electrical pads.
Claims3
An optical transceiver module for use in optical communications networks, comprising:
- a printed circuit board;
- a receiver optical subassembly (“ROSA”);
- and
- a transmitter optical subassembly (“TOSA”), the TOSA comprising:
- an outer casing having a first end and a second end;
- a receptacle attached at a first end of the outer casing;
- and
- an optoelectronic packaging assembly attached at a second end of the outer casing, the optoelectronic packaging assembly comprising:
- an optoelectronic device mounted on a post;
- an enclosure configured to receive the optoelectronic device comprising:
- a base having a via formed therein, wherein the post is disposed in the via;
- a housing having a view port configured to allow the optoelectronic device to send or receive optical signals therethrough, wherein the post is bonded to the via such that the post aligns the optoelectronic device with the view port;
- and
- means for placing the base in electrical communication with the external component using surface mount technology.
