Multi-layer mirror of compound semiconductors including nitrogen and surface light-emitting device with the same

摘要

A surface light-emitting device includes an active layer and a set of reflectors. The reflectors are arranged on both opposite sides of the active layer such that light can be emitted in a direction perpendicular to the active layer. At least a portion of the reflectors includes a plurality of layers of compound semiconductors at least one of which includes nitrogen. Current is injected into the active layer, and the intensity of the light emitted from the surface light-emitting device is changed by the current modulated in accordance with a signal to be transmitted. At least one of the layers of compound semiconductors may also include aluminum.
