摘要：
An optical device for improving conduction and reflectivity and minimizing absorption. The optical device includes a first mirror comprising a first plurality of mirror periods designed to reflect an optical field at a predetermined wavelength, where the optical field has peaks and nulls. Each of the plurality of mirror periods includes a first layer of having a high carrier mobility, a second layer having lower carrier mobility, and a first compositional ramp between the first and second layers. The thicknesses of the first and second layers for at least a portion of the first plurality of mirror periods are established such that the nulls of the optical field occur within the first layer and not within the compositional ramp. At least the portion of the first layers within the first plurality of mirror periods include elevated doping concentrations at locations of the nulls of the optical field.
