Patent ID: 6873799

Claim:
A transceiver optical subassembly comprising: a printed circuit board having a plurality of electrical connection points thereon; a lead frame comprising a plurality of electrical leads connected to said connection points; a solid-state laser connected to selected ones of said plurality of electrical leads; a first photo-detector connected to selected ones of said plurality of electrical leads; and a molded transparent cover member for enclosing said lead frame, said laser and said first photo-detector, said cover member defining an inclined planar surface and a partially cylindrical surface, wherein said inclined planar surface is disposed in a path of emitted light from said laser and has a partially reflective/partially transmissive coating for separating the emitted light into a first beam passing through said cover member along a first optical path and a second beam of reflected light; and wherein said partially cylindrical surface has a reflective coating for focusing and reflecting said reflected light onto a photo-sensitive surface of said first photo-detector providing an electronic representation of optical signals created by said laser; whereby electrical signals supplied to said laser through said electrical leads control the lasing of said laser.
