Abstract: A semiconductor detector (100) for electromagnetic radiation within a wavelength range is disclosed, comprising a first waveguide portion (110), a funnel element (130) configured to funnel incident electromagnetic radiation into a first end (112) of the first waveguide portion, and a second waveguide portion (120) extending in parallel with the first waveguide portion. The second waveguide portion is coupled to the first waveguide portion and configured to out-couple electromagnetic radiation from the first waveguide portion, within a sub-range of the wavelength range. Further, a photodetector (140) including a photoactive layer (144) is arranged at a second end (114) of the first waveguide portion and at an end (124) of the second waveguide portion, and configured to separately detect electromagnetic radiation transmitted through and exiting the first waveguide portion and the second waveguide portion.

Abstract: According to an aspect of the present inventive concept there is provided a device for polarization dependent imaging, comprising:



a detector comprising light sensitive elements;
a plurality of light propagating units, each comprising a polarization splitter having a receiving end for receiving incident light, and comprising a first and a second waveguide.




The first and second waveguides comprise a first and second portion of the receiving end. The first and second waveguides comprise a first and second distributing end, separate from each other. The polarization splitter is configured to propagate received light to the distributing ends. Each of the portions has an elongated shape such that propagation of light in the waveguides is dependent on the light's linear polarization. The elongated shapes are angled with respect to each other, such that the waveguides are configured to propagate different linear polarization directions.
Each light propagating unit is arranged such that light at the first and second distributing ends is output towards a first and second light sensitive element, respectively.

Abstract: An electrically-operable laser device for emitting light at least at a wavelength includes a substrate; at least a first in-plane resonator; a first electrode; a lasing gain medium; and a second electrode. Each resonator includes at least two solid materials having an electrical conductivity below 3 S/m, wherein two or more of the solid materials differ in their refractive indices. The top surface of the first in-plane resonator is planar and has a root mean square roughness below 5 nm. The first resonator is either a) situated above the substrate, or b) comprises a material of the substrate as a first of the at least two solid materials. Any further in-plane resonators, if present, are situated above the substrate.
