Publication number: 20240170917Abstract: A photonic crystal surface-emitting laser includes a light emitting region from which light is emitted in a direction crossing an in-plane direction, and a current blocking region that is adjacent to the light emitting region in the in-plane direction and in which current is less likely to flow than in the light emitting region. The light emitting region and the current blocking region each include a photonic crystal layer. The photonic crystal layer has a first region and second regions periodically arranged in the first region. A refractive index of each of the second regions is different from that of the first region. The light emitting region includes a first semiconductor layer, an active layer, and a second semiconductor layer. The first semiconductor layer, the active layer, and the second semiconductor layer are sequentially stacked on top of one another in an emission direction of the light.Type: ApplicationFiled: March 4, 2022Publication date: May 23, 2024Applicants: Sumitomo Electric Industries, Ltd., Kyoto UniversityInventors: Naoki FUJIWARA, Naoya KONO, Akira FURUYA, Yuki ITO, Susumu NODA, Takuya INOUE, Kenji ISHIZAKI
