Abstract: In example implementations of a vertical-cavity surface-emitting laser (VCSEL), the VCSEL includes a p-type distributed Bragg reflector (p-DBR) layer and a p-type ohmic (p-ohmic) contact layer adjacent to the p-DBR layer. The p-DBR layer may include an oxide aperture and the p-ohmic contact layer may have an opening that is aligned with the oxide aperture. The opening may be filled with a dielectric material. A metal layer may be coupled to the p-ohmic contact layer and encapsulate the dielectric material.

Abstract: In example implementations, an optical connector is provided. The optical connector includes a jumper holder, a base bracket, and an optical ferrule. The jumper holder holds a plurality of ribbon fibers. The base bracket is coupled to an electrical substrate to mate with the jumper holder. The optical ferrule is coupled to an end of each one of the plurality of ribbon fibers.

Abstract: An example system may include a first vertical cavity surface emitting laser (VCSEL) that includes a first integrated polarization locking structure to produce a polarized optical data signal. The system may also comprise a second VCSEL that includes a second integrated polarization locking structure, the second integrated polarization locking structure orthogonal to the first integrated polarization locking structure, to produce an orthogonally polarized optical data signal. Lenses may be disposed on the substrate opposite the first VCSEL, to collimate the polarized optical data signal, and opposite the second VCSEL to collimate the orthogonally polarized optical data signal. A polarization division multiplexer may combine the first collimated polarized optical data signal and the second collimated orthogonally polarized optical data signal.

Abstract: In the examples provided herein, a system includes a loop waveguide; and a grating coupler formed on the loop waveguide to couple light impinging on the grating coupler having a first polarization into the loop waveguide in a first direction, and to couple light having a second polarization, orthogonal to the first polarization, into the loop waveguide in a second direction. The system also includes a ring resonator positioned near the loop waveguide tuned to have a resonant wavelength at a first wavelength to couple light at the first wavelength out of the loop waveguide into the ring resonator. An output waveguide positioned near the ring resonator couples light out of the ring resonator into the output waveguide; and a photodetector detects light propagating out of a first end and a second end of the output waveguide.

Abstract: A high contrast grating optical modulation includes an optical modulator at a front surface of a substrate to modulate received light. The high contrast grating optical modulation further includes a high contrast grating (HCG) lens adjacent to a back surface of the substrate opposite to the front surface to focus incident light onto the optical modulator. The substrate is transparent to operational wavelengths of the focused incident light and the modulated light.

Abstract: An example microring resonator (MRR) based optical device having improved linearity is presented. The optical device includes a first MRR and a first bus waveguide optically coupled to the first MRR. Further, the optical device includes a second MRR optically coupled to the first MRR, and a second bus waveguide optically coupled to the second MRR. The first MRR and the second MRR are formed between the first bus waveguide and the second bus waveguide. The optical coupling between the first MRR and the second MRR increases the linearity in the optical output of the optical device.

Abstract: Examples described herein relate to an optical device that entails phase shifting an optical signal. The optical device includes an optical waveguide having a first semiconductor material region and a second semiconductor material region formed adjacent to each other and defining a junction therebetween. Further, the optical device includes an insulating layer formed on top of the optical waveguide. Moreover, the optical device includes a III-V semiconductor layer formed on top of the insulating layer causing an optical mode of an optical signal passing through the optical waveguide to overlap with the first semiconductor material region, the second semiconductor material region, the insulating layer, and the III-V semiconductor layer thereby resulting in a phase shift in the optical signal passing through the optical waveguide.

Abstract: Coupled-cavity vertical cavity surface emitting lasers (VCSELs) are provided by the present disclosure. The coupled-cavity VCSEL can comprise a VCSEL having a first mirror, a gain medium disposed above the first mirror, and a second mirror disposed above the gain medium, wherein a first cavity is formed by the first mirror and the second mirror. A second cavity is optically coupled to the VCSEL and configured to reflect light emitted from the VCSEL back into the first cavity of the VCSEL. In some embodiments, the second cavity can be an external cavity optically coupled to the VCSEL through a coupling component. In some embodiments, the second cavity can be integrated with the VCSEL to form a monolithic coupled-cavity VCSEL. A feedback circuit can control operation of the coupled-cavity VCSEL so the output comprises a target high frequency signal.
