An emitter for emitting electromagnetic radiation includes a first region for thermally generating electromagnetic radiation, wherein the first region includes a first photonic crystal of the type having a first periodical structure with first holes having a first dimension and being at a first periodicity, so as to define a first dimension-to-periodicity ratio; and a second region for filtering the electromagnetic radiation generated in the first region, wherein the second region includes a second photonic crystal of the type having a second periodical structure with second holes having a second dimension and being at a second periodicity, so as to define a second dimension-to-periodicity ratio, wherein the second dimension-to-periodicity ratio is different from the first dimension-to-periodicity ratio.

Device and method for emitting electromagnetic radiation

A MEMS component includes a semiconductor substrate stack having a first semiconductor substrate and a second semiconductor substrate, wherein the semiconductor substrate stack has a cavity formed within the first and second semiconductor substrates, and wherein at least the first or the second semiconductor substrate has an access opening for gas exchange between the cavity and an environment. A radiation source is arranged at the first semiconductor substrate, and a radiation detector is arranged at the second semiconductor substrate. Two mutually spaced apart reflection elements are arranged in a beam path between the radiation source and the radiation detector, wherein one reflection element is partly transmissive to the emitted radiation from the cavity in the direction of the radiation detector, and wherein an interspace between the two mutually spaced apart reflection elements has a length that is at least ten times the wavelength of the emitted radiation.

MEMS-component

Techniques (e.g., implemented in devices, methods and/or in non-transitory storage units) are used for confining wavelengths, e.g., using a pillar photonic crystal. A semiconductor device includes a pillar photonic crystal including a structure and a plurality of pillars extending from the structure in a height direction, wherein the plurality of pillars form at least one waveguide for electromagnetic radiation at a specific wavelength, the at least one waveguide extending in at least one planar direction, wherein the structure includes a confining layer in doped semiconductor material to support propagation of surface plasmon polaritons.
