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 present disclosure relates to 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. Each integrated optical waveguide comprises an optical resonator for filtering the light guided by the waveguide according to a predetermined spectral component.

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: A system and for distributing data for 3D light field projection and a method thereof. The system comprises input terminals and output terminals that are connectable to pixel elements of a display. Data paths are established between input terminals and output terminals, and are controlled by data switches. The system also comprises a control plane adapted for applying control variables to the data switches. Control switches of the control plane select the control variables which are applied to the data switches. Sequences of control variables and enable variables propagate along at least one first delay line and along at least one second delay line, respectively. Delay units of the at least one first delay line and of the at least one second delay line have a synchronous relationship. During system run-time patterns contained in the stream of input data are detected for determining the sequences of control variables.
