An optical device and method for fabricating an optical device. The optical device comprising: a semiconductor material comprising an active layer configured to emit light when an electrical current is applied to the device and/or to generate an electrical current when light is incident on the active layer, wherein the semiconductor material comprises a first surface and an opposed second surface, from which light is emitted from and/or received by the device, and wherein the first surface defines a first structure comprising the active layer and configured to reflect light emitted from the active layer toward the second surface and/or to reflect light received by the device toward the active layer, and the second surface defines a second structure configured to permit light incident on the second surface at an angle outside a critical angle range to the planar normal to pass therethrough.

LED platform with membrane

An LED module having an LED semiconductor chip mounted directly or indirectly on a platform. The platform is made from silicon and extends laterally beyond the LED semiconductor chip having an active light emitting layer and a substrate. At least one electronic component that is part of the control circuitry for the LED semiconductor chip is integrated in the silicon platform.
