Abstract:
1. A wavelength multiplexer/demultiplexer/compact spectrometer device suitable for analyzing a spectra composition of an optical beam, the device enabling a dispersion of light spectra around a particular wavelength λ c , the device comprising: an input slit for allowing an entry of the optical beam into the device, a location of the input slit being adjustable, and further the location of the input slit X a first output slit for allowing the exiting of a first output optical beam having a first output wavelength λ wherein the curved grating processes the spectra compositions of the optical beam, the curved grating comprising a plurality of grooves, wherein a position of each of the plurality of grooves is adjustable for controlling a performance of the device, such that a path difference between two adjacent grooves is an integral of the center of operation wavelength.
