    • A surface emitting laser device includes a substrate, a lower reflector, an active layer, an upper reflector, and surface emitting lasers configured to emit light. A second phase adjustment layer, a contact layer, a first phase adjustment layer, and a wavelength adjustment layer are successively layered from the active layer side. The total optical thickness from the active layer side of the second phase adjustment layer to the midsection of the wavelength adjustment layer is approximately (2N+1)×λ/4, where λ represents a wavelength of light, and N represents a positive integer. The optical thickness from the active layer side of the second phase adjustment layer to the midsection of the contact layer is approximately Nλ/2. At least two of the surface emitting lasers have the wavelength adjustment layer arranged at different thicknesses and are configured to emit light with different wavelengths.
    • 表面发射激光器件包括衬底,下反射器,有源层,上反射器和被配置为发光的表面发射激光器。 从有源层侧依次层叠第二相位调整层,接触层,第一相位调整层和波长调整层。 从第二相位调整层的有源层侧到波长调整层的中部的总光学厚度大约为(2N + 1)×λ/ 4,其中λ表示光的波长,N表示正整数。 从第二相位调整层的有源层侧到接触层的中部的光学厚度大约为Nλ/ 2。 至少两个表面发射激光器具有布置成不同厚度的波长调整层,并且被配置为发射具有不同波长的光。
