In layer structure 20 of a semiconductor laser of a surface emitting type,
21 and 24 represent an n-type contact layer made of n-type GaN and a
p-layer made of p-type AlGaN, respectively. In the laser, an n-type DBR
layer 22 made of n-type InGaN and a DBR layer 25 made of dielectric are
formed on and below a InGaN active layer 23, respectively, each of which
forms a reflection surface vertical to the z axis. By forming a
reflection surface vertical to the z axis at each of on and above the
active layer 23, a resonator is obtained. Here optical distance between
two reflection facets are arranged to an integral multiple of half a
oscillation wavelength. Consequently, the present invention enables to
produce a semiconductor laser of a surface emitting type easier by far
compared with a conventional invention.
