PROBLEM TO BE SOLVED: To provide a VCSEL capable of effectively performing mode control. SOLUTION: VCSEL 100 includes a p-type GaAs substrate 102; a p-type lower DBR 106 formed on the GaAs substrate 102; an active layer 112 formed on the lower DBR 106 for emitting light; an optical mode control layer 120 formed on the active layer 112 for selectively absorbing or reflecting a light oscillation wavelength to control the mode of laser light; and an upper DBR 124 formed on the optical mode selection layer 120.
