Abstract: An optical system including multiple lenses to receive respective laser beams, and including a combiner (an optical device) to receive the laser beams from the multiple lenses and to combine the laser beams into a single beam. The optical assembly includes a micro-electro-mechanical system (MEMS) mirror to reflect the single beam from the combiner and provide a reflected beam as an exit beam through a window to an object. The optical assembly includes a single-pixel photodetector to collect light reflected from the object.

Abstract: Embodiments of the present disclosure are directed toward an apparatus comprising a frameless MEMS device with a two-dimensional (2D) mirror, in accordance with some embodiments. The apparatus may include a base and a MEMS device disposed on the base. The MEMS device may comprise a rotor having a driving coil disposed around the rotor that is partially rotatable around a first axis, in response to interaction of a first magnetic field provided parallel to the first axis, with electric current to pass through the driving coil. The MEMS device may include a mirror disposed about a middle of the rotor. The mirror may be partially rotatable around a second axis coupled with the rotor and orthogonal to the first axis, in response to interaction of a second magnetic field provided parallel to the second axis, with electric current to pass through the coil. Other embodiments may be described and/or claimed.

Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for a magnetic MEMS apparatus that in some instances may comprise a magnetic circuit and a MEMS device. The magnetic circuit may include two magnets that may be disposed on the substantially flat base and magnetized vertically to the base and in opposite directions to each other to produce a substantially horizontal magnetic field between the magnets. The MEMS device may comprise a mirror and a conductor to pass electric current to interact with the magnetic field created by the magnets. The MEMS device may be disposed substantially between the magnets of the magnetic circuit and above a plane formed by top surfaces of the magnets, to provide an unobstructed field of view for the mirror. The MEMS device may include a ferromagnetic layer to concentrate the magnetic field toward the conductor. Other embodiments may be described and/or claimed.

Abstract: Disclosed are an asymmetric Y-shaped optical waveguide structure and an optical transceiver using the structure. The asymmetric Y-shaped optical waveguide structure includes a main axis optical waveguide extended in a longitudinal direction; and a branch optical waveguide extended from an extension start point in the main axis optical waveguide in a longitudinal direction as much as a predetermined region and then diverged outside. The main axis optical waveguide and the branch optical waveguide have effective refractive indexes, the magnitude relation of which is reversed for optical signals having first and second wavelength range. The optical transceiver includes an asymmetric Y-shaped optical waveguide structure, an optical fiber optically coupled to the structure for transmitting/receiving of the bi-directional optical signal, a laser diode and a photodiode. Accordingly, it is possible to miniaturize the optical transceiver, reduce a packaging cost, and improve reliability of the optical transceiver.

Abstract: A planar optical component is presented that defines an optical path for light propagation in between a first waveguide and an optical fiber. The optical component comprises a waveguide structure defining a transition region between the first waveguide and the optical fiber, the transition region is formed by first and second cladding layers and first and second core segments. The first core segment is formed by a core of said first waveguide having a refractive index n1, and the second core segment is formed by a core of a second connecting waveguide having a refractive index n2<n1. The first and second core segments are physically adjacent to one another all along the transition region such that the first core segment is spaced from at least one of the cladding layers by said second core segment. A cross-sectional size of the first core segment is reduced along the transition region in a direction towards the optical fiber, thereby forming a sloped interface shorted than 1 mm.
