Abstract: Beam couplers and splitters are disclosed herein. An example of a beam coupler and splitter includes a first waveguide having a first waveguide bevel and a bend, the first waveguide bevel to totally internally reflect at least some light incident thereon. A second waveguide includes a second waveguide bevel complementarily shaped to the first waveguide bevel, the second waveguide being coupled to the first waveguide such that i) the first waveguide bevel is offset from the second waveguide bevel so that a first portion of the first waveguide bevel is in direct contact with a first portion of the second waveguide bevel, a second portion of the first waveguide bevel is exposed, and a second portion of the second waveguide bevel is exposed, and ii) a predetermined coupling ratio is achieved.

Abstract: A sensor having a particle barrier is described. In an example, a sensor includes: first and second electrode sets respectively disposed upon a planar support surface and a proof mass that is compliantly displaceable along a first axis substantially parallel to the planar support surface; and a first barrier disposed on the planar support around the first electrode set having a height less than a gap between the planar support and the proof mass to mitigate particle migration into the first or second electrode set.

Abstract: A gas conduit directs a flow of gas from a gas flow source. A surface enhanced luminescence (SEL) stage is within the conduit and includes a substrate and nano fingers projecting from the substrate. A heater heats the nano fingers to a temperature so as to soften the nano fingers such that the nano fingers collapse towards each other to capture molecules entrained in the gas therebetween.
