Patent attributes
Optical micro-modules include an integrated lens holder and microlens for passive coupling of optical signals into an optical fiber. The microlens includes a mounting surface and a curved section having an optical axis. The microlens curved section may be an aspheric silicon lens. The microlens mounting surface is attached to the lens holder mounting surface such that the microlens optical axis is centered with the optical fiber and aligned at a desired focal length from the optical fiber. The lens holder may, for example, be either in mechanical communication with a cable receptacle or be attached to a submount that has a silicon v-groove thereon for receiving an optical fiber. The optical micro-module may be part of other optical devices, for example a transmitter optical sub-assembly or a receiver optical sub-assembly.
