Abstract: Embodiments described herein relate to an imaging device, a method for imaging an object, and a photonic integrated circuit. The imaging device includes at least one photonic integrated circuit. The photonic integrated circuit includes an integrated waveguide for guiding a light signal. The photonic integrated circuit also includes a light coupler optically coupled to the integrated waveguide. The light coupler is adapted for directing the light signal out of a plane of the integrated waveguide as a light beam. The imaging device also includes a microfluidic channel for containing an object immersed in a fluid medium. The microfluidic channel is configured to enable, in operation of the imaging device, illumination of the object by the light beam.

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.

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.
