Abstract
An optical module with directional bias of light beams for improved reception and transmission of optical signals includes a substrate, a photodetector disposed on the substrate, and an optical path control element disposed above the substrate. The optical path control element includes a filter and a reflector. The filter has an upper surface and a lower surface opposite to the upper surface, and the reflector is in contact with the upper surface. A first light beam enters the filter through the lower surface, and is reflected by the reflector to the photodetector. A light source is disposed on the substrate and emits a second light beam. The second light beam is reflected by the lower surface and away from the cavity.

An optical module, comprising:
- an optical port;
- a photodetector;
- a filter having an upper surface and a lower surface opposite to the upper surface;
- and
- a reflector in contact with the upper surface, wherein a first light beam through the optical port enters the filter through the lower surface, and is reflected by the reflector to the photodetector.
An optical module, comprising:
- a cavity having a horizontal axis;
- an optical port connecting the cavity, wherein the optical port is configured to allow light beams to enter or exit the cavity;
- a photodetector configured to sense the light beams entering the cavity;
- a mirror disposed on the horizontal axis in the cavity;
- and
- an optical path control element disposed in the cavity and offset from the horizontal axis, comprising a filter and a reflector, wherein the filter has an upper surface and a lower surface opposite to the upper surface, the reflector is in contact with the upper surface, a first light beam through the optical port enters the filter through the lower surface, and is reflected by the reflector to the photodetector.
