Patent ID: 8115193

Claim:
A vertical resonator type light emitting diode comprising: an active layer; a first reflector layer at a light reflecting side of said active layer, said first reflector layer having one or more pairs of films alternately disposed, one of the pair of films being a relatively high refractive index film of Al 0.45 Ga 0.55 As, the other of the pair of films being a relatively low refractive index film of AlAs; and a second reflector layer at a light emitting side of said active layer, the first reflector layer and the second reflector layer sandwiching said active layer, said second reflector layer having one or more pairs of films alternately disposed, one of the pair of films being a relatively high refractive index film of Al 0.45 Ga 0.55 As, the other of the pair of films being a relatively low refractive index film of AlAs, wherein the number of said pairs in said first reflector layer is not less than 11 and not more than 41, and the number of said pairs in said second reflector layer is not less than 1/10 and not more than ¼ of the number of said pairs in said first reflector layer.
