Research output: Contribution to journalConference articlepeer-review


The incorporation of omni directional reflectors into a semiconductor Light Emitting Diode (LED) was discussed. The omni directional mirror comprises the semiconductor, a metal layer and an intermediate low index dielectric layer of about quarter-wave thickness. The dielectric layer was penetrated by ana array of metallic micro-contacts for enabling electrical conductivity of the reflector structure. It was shown that the optical properties of the ODR exceeded the reflection properties of metals.
