摘要

A semiconductor distributed Bragg reflector (DBR) (110) including a first multilayer structure (103) including a plurality of first semiconductor layers and one or more second semiconductor layers each interposed between a corresponding pair of the plurality of first semiconductor layers; a second multilayer structure (104) including a plurality of third semiconductor layers and one or more second semiconductor layers each interposed between a corresponding pair of the plurality of third semiconductor layers; and a protection layer (105) interposed between the first multilayer structure and the second multilayer structure. The semiconductor layer has a lower decomposition temperature than the first semiconductor layer. The third semiconductor layer has a lower decomposition temperature than the second semiconductor layer.
