Abstract: Devices and techniques for a particle positioning device are generally described. In some examples, a fluid may be introduced to a channel formed on a first surface of a substrate. In various examples, the channel may comprise a periodic dielectric structure etched in a first surface of the substrate and a channel wall material. In some examples, a laser beam may be directed through the channel wall material to the periodic dielectric structure. In various further examples, the laser beam may be reflected from the periodic dielectric structure into an interior region of the channel to form a focal enhancement region of the laser beam in the interior region of the channel adjacent to the periodic dielectric structure. In various examples, a force may be exerted on a particle suspended in the fluid with an electric field gradient generated by the focal enhancement region of the laser beam.

Abstract: Within examples, a laser includes a first electrode and a second electrode; a first transport layer and a second transport layer that are between the first electrode and the second electrode; a gain layer positioned between the first transport layer and the second transport layer, where the gain layer comprises a material having a Perovskite crystal structure; and a substrate on which the first electrode, the second electrode, the first transport layer, the second transport layer, and the gain layer are formed, where a distributed feedback (DFB) waveguide is formed within the first transport layer, and where the laser is configured such that a current flowing through the gain layer between the first electrode and the second electrode causes the gain layer to emit coherent light. Examples also include methods for fabricating the laser, as well as additional lasers and methods for forming those lasers.
