Abstract

Provided is a vertical cavity surface emitting laser element that includes a first substrate, a second substrate, a first DBR layer, and a second DBR layer. The first substrate is formed of a first material and includes an active layer. The second substrate is formed of a second material and is bonded to the first substrate, the second material causing light having a specific wavelength to be transmitted therethrough and being different from that of the first substrate. The first DBR layer is provided on a side of the first substrate opposite to the second substrate and reflects the light having the wavelength. The second DBR layer is provided on a side of the second substrate opposite to the first substrate and reflects the light having the wavelength.
