Title:
SURFACE EMISSION LASER
Document Type and Number:
WIPO Patent Application WO/2023/238621
Kind Code:
A1
Abstract:
Provided is a surface emission laser capable of reducing both series resistance and optical loss. A surface emission laser according to the present technology comprises: a first structure that includes a first reflecting mirror; a second structure that is layered on the first structure and includes a second reflecting mirror; and an active layer that is disposed between the first and second structures. A current injection layer is provided in a range such that the optical intensity of at least the inside of the first and/or second reflecting mirror falls within the range from 1/10 to 2/5 of a peak intensity. Through said surface emission laser according to the present technology, it is possible to provide a surface emission laser capable of reducing both series resistance and optical loss.
