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. In addition, the imaging device includes at least one imaging detector positioned for imaging the object illuminated by the light beam.

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: An example embodiment relates to a photonic integrated circuit device and a method for its manufacture. An example device includes a planar detector having at least one photodetector. The device may further include a waveguide layer arranged substantially parallel to the planar detector, the waveguide layer including a first integrated waveguide for guiding a first light signal. A cavity may be formed in the waveguide layer in a region spaced away from the edges of the waveguide layer such as to terminate the first integrated waveguide in that region. A first reflective surface may be provided in the cavity to reflect the first light signal guided by the first integrated waveguide toward a first photodetector of the planar detector.

Abstract: An example embodiment may include an interferometer. The interferometer may include a multimode waveguide with an input waveguide optically coupled to a first side of the multimode waveguide, for feeding a light signal to the multimode waveguide. The interferometer may also include a first waveguide at one end optically coupled to a second side of the multimode waveguide, and at the other end terminated by a first waveguide mirror. The interferometer may also include a second waveguide at one end optically coupled to the second side of the multimode waveguide and at the other end terminated by a second waveguide mirror. The multimode waveguide may be adapted to distribute the light signal towards the first and second waveguide mirror via the first waveguide and via the second waveguide.
