    摘要： The device is an optoelectronic device or transparent waveguide device that comprises a growth surface, a growth mask, an optical waveguide core mesa and a cladding layer. The growth mask is located on the semiconductor surface and defines an elongate growth window having a periodic grating profile. The optical waveguide core mesa is located in the growth window and has a trapezoidal cross-sectional shape. The cladding layer covers the optical waveguide core mesa and extends over at least part of the growth mask. Such devices are fabricated by providing a wafer comprising a growth surface, growing an optical waveguide core mesa on the growth surface by micro-selective area growth at a first growth temperature and covering the optical waveguide core mesa with cladding material at a second growth temperature, lower than the first growth temperature.

    摘要： In one aspect, a VCSEL includes a base region that has a vertical growth part laterally adjacent a first optical reflector and a lateral growth part that includes nitride semiconductor material vertically over at least a portion of the first optical reflector. An active region has at least one nitride semiconductor quantum well vertically over at least a portion of the lateral growth part of the base region and includes a first dopant of a first electrical conductivity type. A contact region includes a nitride semiconductor material laterally adjacent the active region and a second dopant of a second electrical conductivity type opposite the first electrical conductivity type. A second optical reflector is vertically over the active region and forms with the first optical reflector a vertical optical cavity overlapping at least a portion of the at least one quantum well of the active region. A method of fabricating a VCSEL also is described.

    摘要： The electroabsorption modulator comprises a p-i-n junction structure that includes an active layer, a p-type cladding layer and an n-type cladding layer with the active layer sandwiched between the cladding layers. The electroabsorption modulator additionally comprises a quantum well structure located within the active layer. The p-type cladding layer comprises a layer of heavily-doped low-diffusivity p-type semiconductor material located adjacent the active layer that reduces the extension of the depletion region into the p-type cladding layer when a reverse bias is applied to the electroabsorption modulator. The reduced extension increases the strength of the electric field applied to the quantum well structure by a given reverse bias voltage. The increased field strength increases the extinction ratio of the electroabsorption modulator.
