ABSTRACT:
The present invention provides an optical device and a surface emitting type device which have high efficiency and a stable operation and are manufactured at high manufacturing yield. The optical device and the surface emitting type device are characterized in that they have a distributed Bragg reflector (DBR) including a plurality of semiconductor layers made of a nitride semiconductor with substantially same gaps therbetween. Further, the optical device and the surface emitting type device are characterized in that they have a distributed Bragg reflector (DBR) in which a plurality of semiconductor layers made of nitride semiconductor and a plurality of organic layers made of organic material are alternately laminated.
