Abstract
An integrated optical coupler includes multiple ports and a beam discriminating element. Optical elements are provided for directing light to and from the ports and the beam discriminating element. These optical elements may include two optical elements created on the same surface of a substrate. All of the optical elements needed for directing the light may be formed on a transparent substrate or on a structure in the optical path bonded to the substrate. The optical elements may output light of the different wavelengths at the same angle or may be dispersive. The beam discriminating element may discriminate on the basis of wavelength or polarization.
