Abstract: A Fourier transform spectrometer comprising an interferometer comprising a fixed mirror, a movable mirror and a detector, wherein: the mirrors are positioned parallel to each other and form an optical cavity; the movable mirror is operable to move relative the fixed mirror to change the size of the optical cavity; a first mirror of the mirrors is positioned such that light received from a sample enters the optical cavity through a back of the first mirror; the detector is positioned and operable to detect light which has exited the optical cavity through a back of the second mirror of the mirrors and output an interferogram; and the mirrors are distanced from each other such that the movable mirror is at or can move to a position where at least two paths to the detector for received light reflected within the interferometer are equal length.

Abstract: A plasmonic sensor device includes a light source, configured to generate coherent light; a metallic film, at least partially covered on one side by analyte molecules; at least one micromirror that is rotatable about at least one axis of rotation, which is positioned and developed in such a way that the coherent light is able to be guided at an angle of incidence to one side of the metallic film, the angle of incidence being variable by the rotating of the at least one micromirror about the at least one axis of rotation; and a detector configured to determine the intensity of the light guided onto the metallic film and reflected again from there, as a function of the angle of incidence, the coherent light generated by the light source being in such a state that surface plasmons are excitable in the metallic film depending on the angle of incidence.

Abstract: An apparatus (100) comprising: semiconductor (2); and an asymmetric electrode arrangement (10) comprising a first electrode (11), a second electrode (12) separated from the first electrode across a portion of the semiconductor and at least one surface plasmon polariton generator (20) associated with at least the first electrode (11).
