Abstract

A GaN based light emitting diode device which emits polarized light or light of various degrees of polarization for use in the creation of optical devices. The die are cut to different shapes, or contain some indicia that are used to represent the configuration of the weak dipole plane and the strong dipole plane. This allows for the more efficient manufacturing of such light emitting diode based optical devices.
