    Abstract: Embodiments described herein relate to a light coupler, a photonic integrated circuit, and a method for manufacturing a light coupler. The light coupler is for optically coupling to an integrated waveguide and for out-coupling a light signal propagating in the integrated waveguide into free space. The light coupler includes a plurality of microstructures. The plurality of microstructures is adapted in shape and position to compensate decay of the light signal when propagating in the light coupler. The plurality of microstructures is also adapted in shape and position to provide a power distribution of the light signal when coupled into free space such that the power distribution corresponds to a predetermined target power distribution. Each of the microstructures forms an optical scattering center. The microstructures are positioned on the light coupler in accordance with a non-uniform number density distribution.

    Abstract: The disclosed technology generally relates to semiconductor devices, and more particularly to a device configured as one or both of a spin wave generator or a spin wave detector. In one aspect, the device includes a magnetostrictive film and a deformation film physically connected to the magnetorestrictive film. The device also includes an acoustic isolation surrounding the magnetostrictive film and the deformation film to form an acoustic resonator. When the device is configured as the spin wave generator, the deformation film is configured to undergo a change physical dimensions in response to an actuation, where the change in the physical dimensions of the deformation film induces a mechanical stress in the magnetostrictive film to cause a change in the magnetization of the magnetostrictive film. When the device is configured as the spin wave detector, the magnetostrictive film is configured to undergo to a change in physical dimensions in response to a change in magnetization, wherein the change in the physical dimensions of the magnetostrictive film induces a mechanical stress in the deformation film to cause generation of electrical power by the deformation film.

    Abstract: A built-in self-calibration system and method for a micro-mirror array device, for example, operating as a variable focal length lens is described. The calibration method comprises determining a capacitance value for each micro-mirror element in the array device at a number of predetermined reference angles to provide a capacitance-reference angle relationship. From the capacitance values, an interpolation step is carried to determine intermediate tilt angles for each micro-mirror element in the array. A voltage sweep is applied to the micro-mirror array and capacitance values, for each micro-mirror element in the array, are measured. For a capacitance value that matches one of the values in the capacitance-reference angle relationship, the corresponding voltage is linked to the associated tilt angle to provide a voltage-tilt angle characteristic which then stored in a memory for subsequent use.

    Abstract: The present disclosure describes a device for measuring an optical absorption property of a fluid as function of wavelength. The device comprises a broadband light source for emitting light, a plurality of integrated optical waveguides for guiding this light and a light coupler for coupling the emitted light into the integrated optical waveguides such that the light coupled into each integrated optical waveguide has substantially the same spectral distribution. The device also comprises a microfluidic channel for containing the fluid, arranged such as to allow an interaction of the light propagating through each waveguide with the fluid in the microfluidic channel, and a plurality of spectral analysis devices optically coupled to corresponding waveguides—such as to receive the light after interaction with the fluid. The spectral analysis devices are adapted for generating a signal representative of a plurality of spectral components of the light.

    Abstract: An example embodiment may include an optical system for obtaining radiation coupling between two waveguides positioned in a non-coplanar configuration. The optical system may include a first waveguide positioned in a first plane and a second waveguide positioned in a second plane. The first waveguide may be stacked over the second waveguide at a distance adapted to allow evanescent coupling between the first waveguide and the second waveguide. The first waveguide and the second waveguide may be configured such that the coupling is at least partly tolerant to relative translation or rotation of the first waveguide and the second waveguide with respect to each other.
