Title:
SURFACE LIGHT-EMITTING LASER
Document Type and Number:
Japanese Patent JP2022002300
Kind Code:
A
Abstract:
To provide a surface light-emitting laser which is improved in modulation bandwidth improved.SOLUTION: A surface light-emitting laser 1 comprises a main resonator 10 and a plurality of external resonators 30. The main resonator 10 has a VCSEL structure 12, and also has an electrode for modulation and an emission window for laser beam. Each external resonator 30 has a VCSEL structure in which an active layer mutually connects with the main resonator 10, and is laterally coupled to the main resonator 10.SELECTED DRAWING: Figure 1
