Abstract: Examples herein relate to optical modules. In particular, implementations herein relate to optical modules that include top-emitting VCSELs and/or top-entry photodetectors. The optical modules include a first interposer having opposing first and second sides and a second interposer having opposing first and second sides. The optical modules include a plurality of top-emitting vertical-cavity surface-emitting lasers (VCSELs) coupled to the second interposer and a plurality of electrical conductors forming electrical paths between electrical contacts of the top-emitting VCSELs and the second side of the second interposer. The VCSELs are configured to emit optical signals having different wavelengths. The optical signals are configured to be combined and transmitted over a single optical fiber.

Abstract: A VCSEL device includes a substrate and a first DBR structure disposed on the substrate. The VCSEL device further includes a cathode contact disposed on a top surface of the first DBR structure. In addition, the VCSEL device includes a VCSEL mesa that is disposed on the top surface of the first DBR structure. The VCSEL mesa includes a quantum well, a non-circularly-shaped oxide aperture region disposed above the quantum well, and a second DBR structure disposed above the non-circularly-shaped oxide aperture region. In addition, the VCSEL mesa includes a selective polarization structure disposed above the second DBR structure and an anode contact disposed above the selective polarization structure.

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: One example includes an optical coupler. The optical coupler includes a waveguide formed in a first layer of a layered structure that is to propagate an optical signal. The waveguide includes an end portion. The optical coupler also includes a turning mirror that includes a bulk structure and a reflective material deposited on an angular face of the bulk structure to form a surface of the turning mirror. The bulk structure can have a greater cross-sectional size than a cross-sectional size of the waveguide, such that the angular face extends above the first layer of the layered structure and extends into a second layer of the layered structure below the first layer. The surface of the turning mirror can be arranged to reflect the optical signal that is provided from the end portion of the waveguide.

Abstract: In the examples provided herein, an apparatus has a first substrate upon which one or more first filters have been fabricated on a first surface of the first substrate. The apparatus also has a second substrate upon which one or more second filters have been fabricated on a second surface of the second substrate, wherein the one or more first filters and the one or more second filters each transmit a different band of wavelengths. Additionally, the apparatus has a bonding material that bonds the first substrate to the second substrate.

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: A bottom-emitting vertical-cavity surface-emitting laser (VCSEL) structure includes a first substrate permitting the passage of light therethrough, an n-doped distributed Bragg reflector (nDBR), a p-doped distributed Bragg reflector (pDBR), one or more active layers, at least one of a high contrast grating mirror and a dielectric-enhanced metal mirror, and a plurality of layers, where the VCSEL structure is configured to be flip chipped to a second substrate. The pDBR and the nDBR define a laser cavity extending vertically therebetween and containing the one or more active layers. The at least one of a high contrast grating mirror and a dielectric-enhanced metal mirror may be disposed over the pDBR. The plurality of layers may be disposed over the at least one of the high contrast grating mirror and the dielectric-enhanced metal mirror to optically and hermetically seal the laser cavity.
