High-brightness high-power semiconductor light-emitting device and method for manufacturing same

Abstract

A high-brightness high-power semiconductor light-emitting device and a method for manufacturing same. The high-brightness high-power semiconductor light-emitting device includes: a semiconductor substrate layer; a modulation structure arranged on the semiconductor substrate layer, where the modulation structure includes: a carrier modulation active layer; a modulation tunnel junction arranged on a side of the carrier modulation active layer away from the semiconductor substrate layer; and a cavity extension layer arranged on a side of the modulation tunnel junction away from the carrier modulation active layer; a first active layer arranged on a side of the modulation structure away from the semiconductor substrate layer, where a carrier concentration in the carrier modulation active layer is less than a carrier concentration in the first active layer; and a first current-limiting layer arranged on a side of the first active layer away from the modulation structure. The high-brightness high-power semiconductor light-emitting device can have a high level of integration, high reliability, and low costs while implementing high brightness and high power.
