SURFACE EMITTING LASER
Document Type and Number:
WIPO Patent Application WO/2024/095620
Kind Code:
A1
Abstract:
Provided is a surface emitting laser that can apply a desired loss to a transverse mode. A surface emitting laser according to the present invention comprises an active layer, a first structure having a concave mirror disposed on one side of the active layer, and a second structure having a reflecting mirror disposed on the other side of the active layer, wherein: the first structure and/or the second structure are/is provided with a transverse mode adjustment region; when a region surrounding a light emitting region of the active layer in a plan view is defined as a first region, and a region surrounding the first region is defined as a second region, the transverse mode adjustment region has at least the first region among the first and second regions; and in a case where the transverse mode adjustment region has only the first region among the first and second regions, when the shortest distance and the longest distance, among distances from the area centroid of the transverse mode adjustment region to the inner edge of the first region, are respectively defined as DS and DL, 1≤DL/DS≤10 is established.
