Abstract

An optical device (306) includes an internal cavity and an emitter (102) disposed in the internal cavity (210). The emitter is operable to emit a first light wave (220). The optical device also includes a detector (104) disposed in the internal cavity. The detector is operable to detect a second light wave (225) that is based on the first light wave. The second light wave is susceptible to being coupled with an undesired light wave (235) that is based on the first light wave. The optical device further includes an interference filter (310) disposed on the detector. The interference filter has a filter property that causes the interference filter to attenuate the interfering light wave.
