  • Method for fabricating optical device
    Patent number: 8537867
    Abstract: A method for fabricating an optical device including: a first step of preparing a carrier having a first area and a second area, both edges of the second area having a wall of a step, one edge of the second area being adjacent to the first area, the first area having a first thickness, the second area having a second thickness larger than the first thickness, a second step of mounting the carrier on a temperature control device after the first step, and a third step of mounting a first optical component on the first area of the carrier after the second step.

  • OPTICAL MODULE WITH DEVICE UNIT ELECTRICALLY ISOLATED FROM OPTICAL RECEPTACLE
    Publication number: 20120288239
    Abstract: An optical module is disclosed where an optical coupling efficiency between an optical device and an external fiber may be improved. The optical module includes an optical receptacle and a device unit assembled with the optical receptacle only via a stub as forming a gap to isolate these two components. The gap is filled with insulating resin or tightly covered by an insulating ring to reinforce the stub to be hard for an increased moment by the optical assemblies in the device unit.
