Fourier-transform optical spectrometer Ghent University
A Fourier-transform optical spectrometer (102, 104) comprises a planar slab (106); a first optical waveguide (114); a second optical waveguide (116), wherein the first optical waveguide (114) and the second optical waveguide (115) each is in the form of a local modification of the slab (106) and are laterally disposed at the slab (106) parallel to each other; and an optical detector system (108) connected to an unmodified section (112) of the slab (106) and segmented and extending in parallel to the first optical waveguide (114) and the second optical waveguide (116), wherein the first ...
