Patent ID: 7422377

Claim:
A transmitter optical micro-module comprising: a transmitter sub-module comprising: a light emitter mounted upon a silicon substrate; a lens holder mounted upon the silicon substrate adjacent the light emitter, the lens holder having a mounting surface; a lens attached to the mounting surface of the lens holder at a desired focal distance from the light emitter for receiving an emitted optical signal from the light emitter and collimating the optical signal; and a back monitor positioned adjacent a back facet of the light emitter for monitoring the wavelength and/or power of the light emitted by the light emitter; and a light coupling sub-module comprising: a submount comprising a silicon substrate, the submount being in mechanical communication with an optical fiber receptacle; a lens holder attached to the submount, the lens holder having a mounting surface; and a microlens comprising: a mounting surface; and a curved section having an optical axis; wherein the microlens mounting surface is attached to the lens holder mounting surface and the optical axis is aligned with the optical fiber receptacle such that, when an optical fiber is connected to the optical fiber receptacle, an optical signal can be effectively created by the light emitter, received by the microlens, and coupled into the optical fiber.
