    摘要： A surface emitting laser device includes a substrate (101), a lower reflector (102), an active layer (104), an upper reflector (106, 113), and surface emitting lasers (11-14) configured to emit light. A second phase adjustment layer (108), a contact layer (109), a first phase adjustment layer (111), and a wavelength adjustment layer (112) are successively layered from the active layer side. The total optical thickness from the active layer side of the second phase adjustment layer (108) to the midsection of the wavelength adjustment layer (112) 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 (108) to a midsection of the contact layer (109) is approximately Nλ/2. At least two of the surface emitting lasers (11-14) have the wavelength adjustment layer (112) arranged at different thicknesses and are configured to emit light with different wavelengths.

    摘要： A surface emitting laser element includes a lower Bragg reflection mirror; an upper Bragg reflection mirror; and a resonator region formed between the lower Bragg reflection mirror and the upper Bragg reflection mirror, and including an active layer. A wavelength adjustment region is formed in the lower Bragg reflection mirror or the upper Bragg reflection mirror, and includes a second phase adjustment layer, a wavelength adjustment layer and a first phase adjustment layer, arranged in this order from a side where the resonator region is formed. An optical thickness of the wavelength adjustment region is approximately (2N+1)×λ/4, and the wavelength adjustment layer is formed at a position where an optical distance from an end of the wavelength adjustment region on the side of the resonator region is approximately M×λ/2, where λ is a wavelength of emitted light, M and N are positive integers, and M is N or less.

    摘要： Vertical-cavity surface-emitting lasers ("VCSELs") and VCSEL arrays are disclosed. In one aspect, a surface-emitting laser includes a grating layer having to form a resonant cavity with a reflective layer for a wavelength of light to be emitted from a light-emitting layer and an aperture layer disposed within the resonant cavity. The VCSEL includes a charge carrier transport layer disposed between the grating layer and the light-emitting layer. The transport layer has a gap adjacent to the sub-wavelength grating and a spacer region between the gap and the light-emitting layer. The spacer region and gap are dimensioned to be substantially transparent to the wavelength. The aperture layer directs charge carriers to enter a region of the light-emitting layer adjacent to an aperture in the aperture layer and the aperture confines optical modes to be emitted from the light-emitting layer.
