Abstract: An integrated photonic device comprises: an input waveguide configured to extend in an input plane, and an output waveguide configured to extend in an output plane, wherein the output plane is parallel to or contained within the input plane; an input coupler optically coupled to the input waveguide, wherein the input coupler is configured to redirect a light signal out of the input waveguide and the input plane; a light property modifier configured to receive the light signal from the input coupler and reflect the light signal towards the output plane, wherein the light property modifier is configured to selectively adjust an optical path length of the light signal; and an output coupler optically coupled to the output waveguide, wherein the output coupler is configured to receive the reflected light signal from the light property modifier and redirect the light signal into the output waveguide and the output plane.

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: A resonator for spin waves, wherein the resonator comprises a stack of material layers arranged on a substrate, a waveguide structure formed in at least one material layer in the stack and configured to propagate a spin wave and to confine a spin wave propagating in a waveguide element of the waveguide structure, such that a spin wave of a selected frequency propagating in the waveguide structure is arranged to resonate in the waveguide structure. The resonator further comprises a control mechanism formed in at least one material layer in the stack and configured to adapt at least one property of the waveguide structure for tuning the resonance frequency of the waveguide structure.
