Title: High reflectivity mirrors and method for making same

Patent · Tue Jun 07 00:00:00 EDT 2016

OSTI ID:1255950

Heikman, Sten; Jacob-Mitos, Matthew; Li, Ting; Ibbetson, James

A composite high reflectivity mirror (CHRM) with at least one relatively smooth interior surface interface. The CHRM includes a composite portion, for example dielectric and metal layers, on a base element. At least one of the internal surfaces is polished to achieve a smooth interface. The polish can be performed on the surface of the base element, on various layers of the composite portion, or both. The resulting smooth interface(s) reflect more of the incident light in an intended direction. The CHRMs may be integrated into light emitting diode (LED) devices to increase optical output efficiency
