Abstract
An optical module includes a module body on which at least one photo diode is mounted, a filter holder inserted into the module body, and a thin film filter mounted on the filter holder in order to guide optical signals towards photo diodes in such a manner that optical signals with corresponding wavelengths are received in the photo diodes. The filter holder, on which the thin film filters are mounted, is fabricated separately from the module body and houses active elements, such as the laser diode and photo diodes. The filter holder is inserted into the module body thereafter, so the optical module is easily fabricated at a low cost and in a simple manner.
Claims19
An optical module for a multi-wavelength, comprising:
- a module body on which at least one photo diode is mounted;
- a filter holder disposed in the module body;
- and
- at least one thin film filter mounted on the filter holder to guide optical signals towards the photo diodes in such a manner that optical signals having wavelengths corresponding the photo diodes can be received therein.
A method for fabricating an optical module, the method comprising the steps of:
- providing a module body on which at least one photo diode is mounted;
- providing a filter holder on which at least one thin film filter is mounted to guide optical signals towards the photo diodes in such a manner that optical signals having wavelengths corresponding to the photo diodes can be received therein;
- and
- inserting the filter holder inside the module body.
The method of 16, further providing a lens aligned in an optical path of the optical signals between the thin film filter and the photo diode.
