Abstract
The present invention provides an interferometer. In one embodiment, the interferometer includes a translucent body having a first portion and a second portion, where the second portion has at least three internal reflective sides. The interferometer also includes an interface between the first and second portions, configured to reflect a portion of an optical signal received through the first portion and transmit a remaining portion of the optical signal into the second portion. Also disclosed are a method of manufacturing an interferometer and a transmitter incorporating the interferometer or the method.
