Abstract: A light emitting diode includes a diode structure containing a quantum well, an enhancement layer, and a barrier layer between the enhancement layer and the quantum well. The enhancement layer supports plasmon oscillations at a frequency that couples to photons produced by combination of electrons and holes in the quantum well. The barrier layer serves to block diffusion between the enhancement layer and the diode structure.

Abstract: Vertical-cavity surface-emitting lasers (“VCSELs”) and VCSEL arrays are disclosed. In one aspect, a surface-emitting laser includes a grating layer having a sub-wavelength grating 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.

Abstract: A high contrast grating optoelectronic apparatus includes an optoelectronic device at a front surface of a substrate. The optoelectronic device is to one or both of emit light and detect light through a back surface of the substrate opposite the front surface. A high contrast grating (HCG) lens is adjacent to and spaced apart from the back surface of the substrate by a spacer. The spacer includes one or both of a wafer-bonded substrate and a cavity. The HCG lens is to focus the light.

Abstract: Coupling modulation of an optical resonator employs a variable modal index to provide modulation of optical signal coupling. A coupling-modulated optical resonator includes an optical resonator having a coupled portion and a bus waveguide having a modulation section adjacent to and coextensive with and separated by a gap from the coupled portion. The modulation section is to modulate coupling of an optical signal between the optical resonator and the bus waveguide according to a variable difference between a modal index of the bus waveguide modulation section and a modal index of the optical resonator coupled portion.
