Classification: CPC G  H  B | IPC B  G  H

Claim 16:
17. A light emitting diode (LED) device comprising:
a light emitting semiconductor structure that in operation emits light having a peak wavelength,
a transparent conducting metal oxide layer adjacent to the light emitting semiconductor structure; and
a reflective structure comprising:
a distributed Bragg reflector (DBR) having a first thickness and configured to reflect light emitted by the light emitting semiconductor structure at the peak wavelength and incident with transverse-electric (TE) polarization on the reflective structure; and
a reflective layer configured to reflect light emitted by the light emitting semiconductor structure at the peak wavelength and incident with TM polarization on the reflective structure, the reflective layer having a second thickness that is a same as or thinner than the first thickness of the DBR.
