Abstract
The present technology provides a surface emitting laser capable of stabilizing emission characteristics against change in driving temperature. The present technology provides a surface emitting laser including: first and second multilayer film reflectors; a plurality of active regions stacked between the first and second multilayer film reflectors; and a tunnel junction disposed between at least one set of two adjacent active regions, in which the plurality of active regions includes at least two of the active regions in which peak wavelengths of emission spectra are different from each other. According to the present technology, a surface emitting laser capable of stabilizing emission characteristics against change in driving temperature is provided.
