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: Provided are a dual coupler device configured to receive lights of different polarization components, a spectrometer including the dual coupler device, and a non-invasive biometric sensor including the spectrometer. The dual coupler device may include, for example, a first coupler layer configured to receive a light of a first polarization component among incident lights. and a second coupler layer configured to receive a light of a second polarization component among the incident lights, wherein a polarization direction of the light of the first polarization component is perpendicular to a polarization direction of the light of the second polarization component. The first coupler layer and the second coupler layer may be spaced apart from each other and extended along a direction in which the light propagates in the first coupler layer and the second coupler layer.

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.
