Title:
SURFACE EMITTING LASER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
Japanese Patent JP2004221492
Kind Code:
A
Abstract:
To reduce the resistance of a distributed Bragg reflection layer while suppressing a resonator loss.
The non-doped distributed Bragg reflection layer 6 of the surface emitting laser is divided into a light reflecting region R1 forming the resonator of the surface emitting laser, and a low-resistance region R2 in the reflection layer 6 playing a role of electric conduction. A heavily doped p-type diffusion layer 7 is formed in the low-resistance region R2.
