Semiconductor light emitting system
摘要:
A semiconductor light emitting element, a laser or a light emitting diode which is deposited on a first area of a semiconductor substrate, which also carries a microlens for focusing or diverging an output beam of the light emitting element on a second area of the substrate. Both the light emitting element and the microlens are deposited on a substrate through a photolithoetching process, and an alignment of an optical axis of the light emitting element and an optical axis of the microlens is accomplished in the steps of producing a light emitting semiconductor system. Thus, a semiconductor light emitting system which functions not only to generate light but also to focus or diverge the light, and is small in size and light in weight, can be obtained.
