Abstract
A laser diode is disposed on a silicon substrate. An optical fiber is inserted into a ferrule with a substantially constant cross-section. The ferrule is disposed at a V-shape groove formed on the substrate to optically couple the optical fiber with the laser diode.
Claims36
An optical module, comprising:
- a substrate on which a groove is formed;
- a laser diode disposed on said substrate;
- an optical fiber;
- and
- a ferrule with a substantially constant cross-section, wherein said optical fiber is disposed in said ferrule and said ferrule is disposed in the groove of said substrate to optically couple said optical fiber with said laser diode.
2 more elements
A method of making an optical module, comprising:
- forming a groove on a substrate;
- mounting a laser diode on the substrate;
- and mounting a ferrule with a substantially constant cross-section and with an optical fiber positioned therein, in the groove of the substrate to optically couple the optical fiber with the laser diode.
