Abstract:
Micromonochromator formed in an integrated substrate and including:at least one entry means for light guidance; at least one exit means for light guidance; means for diffraction, the diffraction means being between the at least one entry means and the at least one exit means and along the light way therebetween, and being integrated in the substrate; and mobile means for light guidance, the mobile means being between the at least one entry means and the at least one exit means and along the light way therebetween, and including at least one mobile beam integrated in the substrate and equipped with at least one light guide, the mobile beam being able to sweep the diffraction means in a continuous manner; whereby one desired wavelength carried by an optical wave that enters the at least one entry means is recovered in the at least one exit means when the mobile beam is adjusted to a selected position with respect to the diffraction means.
