ABSTRACT:
A surface emitting laser that oscillates at a wavelength λ includes an upper reflector, a lower reflector, an active layer, and a spacer layer. The spacer layer is a laminated structure that includes a first semiconductor sublayer having a composition of AlxGa1-xAs (1≧x>0) and a second semiconductor sublayer having a composition of AlyGa1-yAs (1>y>0 and x>y).
