Title:

SURFACE EMISSION LASER

Document Type and Number:

Japanese Patent JP2022002299

Kind Code:

A

Abstract:

To provide a surface emission laser with improved modulation bandwidth.SOLUTION: A surface emission laser 1C has a vertical cavity surface emission laser (VCSEL) structure 60. The VCSEL structure 60 has an aperture 80 due to a current constriction structure. In the upper distributed bragg reflector (DBR) of the VCSEL structure 60, an optical discontinuity member 82 is formed in a region separated from the aperture 80.SELECTED DRAWING: Figure 15
