Abstract: Hybrid subtractive-additive production of a superconducting multi-layer transition-edge sensor includes: forming a superconductor layer; forming a patterning photoresist on the superconductor layer; forming a sensor pattern in the patterning photoresist; subtractively forming, from the superconductor layer, the superconductor sensor layer; removing the patterning photoresist from the superconductor sensor layer; forming a template photoresist on the superconductor sensor layer; forming an inverse normal metal layer pattern in the template photoresist and exposing a bilayer portion of the superconductor sensor layer for addition of a normal metal layer; and additively forming the normal metal layer on the superconductor sensor layer such that the sensor pattern is interposed between the normal metal layer and the substrate.

Abstract: A fiber-to-chip coupler includes a substrate, a waveguide on a top surface of the substrate, an optical fiber axially aligned to the waveguide, and a cap. The waveguide has a uniform region with uniform width and a tapered-waveguide region having a width that adiabatically increases from a minimum width to the uniform width. The optical fiber has a tapered fiber tip having a minimum core diameter, a cylindrical section having a maximum core diameter, and a tapered-fiber section therebetween. The optical fiber is located at least in part above the tapered-waveguide region, and has a core diameter that adiabatically decreases within a taper length of the tapered-fiber section. The cap extends from the tapered fiber tip toward the cylindrical section, is formed of a second material having a cap refractive index that exceeds a refractive index of the optical fiber, and includes a cap-region disposed on the tapered-waveguide region.

Abstract: An optical flow meter includes a substrate; a microchannel with a fluid receiver; a fluid transmitter; a fluid member with an optical interaction region; a photo interaction region; an analytical light path, such that analytical light interacts with an analyte in a photo interaction region subsequent to an interaction of a pre-analyte with activation light in an optical interaction region to produce analyte; and a detection light path disposed in the substrate, arranged at an oblique angle or right angle to the fluid member proximate to the photo interaction region, and that: receives the photoanalyte light from the photo interaction region; and communicates the photoanalyte light from the microchannel to a photodetector, the optical flow meter determines a flow rate of the analyte.

Abstract: A quantum waveguide infrared photodetector includes: a photon absorption layer that receives infrared photons propagating longitudinally along a longitudinal length of the photon absorption layer, converts the infrared photons into electrons, and communicates the electrons to a conductor layer; a first conductor layer that receives a first electrical potential; and a second conductor layer that receives a second electrical potential, wherein electrons produced by the photon absorption layer are communicated from the photon absorption layer: to the first conductor layer when the first electrical potential is more positive than the second electrical potential, and to the second conductor layer when the second electrical potential is more positive than the first electrical potential, an electrical current produced by the electrons is proportional to an amount of absorption of the infrared photons in the photon absorption layer.
