Patent number: 10036839Abstract: A direction-selective interferometric optical filter for spectrometric devices, at least includes an arrangement of two layered one-dimensional photonic structures. Each of the two structures contains a defect layer, and each photonic structure has a dispersion function in the energy momentum space (E, kx, ky), wherein kx and ky are momentum components of transmitted photons of the photonic structures for a defined energy (frequency/wavelength) E in the energy momentum space. Both photonic structures have opposite interfaces which are at a plane-parallel distance from one another. In this case, the dispersion functions of both photonic structures cross or intersect in the energy momentum space and produce a cut set of rays of waves on the surfaces of the dispersion functions at a particular energy, wherein a ray of waves contains waves selectively chosen through the filter at an angle, while other waves are reflected by the filter at other angles.Type: GrantFiled: October 7, 2015Date of Patent: July 31, 2018Assignee: TECHNISCHE UNIVERSITÄT DRESDENInventors: Maik Langner, Hartmut Fröb, Vadim G.
