Abstract
An optical module includes: an optical element including a light emitting section which emits a light signal and two external terminals on a light emitting surface; an optical fiber configured to transmit the light signal; a ferrule having an insertion hole into which the optical fiber is inserted; and a wiring board where two connection electrodes provided to a first main surface are respectively bonded to the two external terminals via bumps, and the ferrule is provided to a second main surface, wherein the light emitting surface of the light emitting element is inclined with respect to the first main surface at a predetermined inclination angle based on heights of the bumps.
Claims9
An optical module comprising:
- an optical element including an optically functional region which emits or receives a light signal and two external terminals on a front surface of the optical element;
- an optical fiber configured to transmit the light signal;
- a ferrule having an insertion hole, the optical fiber being inserted into the insertion hole;
- and
- a wiring board having a first main surface and a second main surface, two connection electrodes provided to the first main surface being respectively bonded to the two external terminals of the optical element via bumps, the ferrule being provided to the second main surface, wherein
- the front surface of the optical element is inclined with respect to the first main surface at a predetermined inclination angle based on heights of the bumps.
