Abstract
High bandwidth angle modulated communications may be obtained using an incoherent/broadband 'white light' source. The light is passed through interferometer arms before and after a communication link. The light is modulated in a transmitter signal optical angle modulator and in a reference optical angle modulator. By locating an interferometer and light source at a receiver, the light passes through the interferometer both before and after the optical link to the transmitter. A balanced detector implements subtraction of non-interfering light.
