Abstract (en)
[origin: WO02077687A2] The invention concerns an integrated optical spectrometer with high spectral resolution, in particular for high-speed telecommunications and metrology, and a method for making same. Said spectrometer comprises at least an elementary spectrometer which includes an optical phase grating including a set of micro-guides (12) and formed on a cleaved planar optical guide (14), reflecting means (24, 30, 32, 34) adapted to successively reflect radiation derived from the set of micro-guides, so as to propagate said radiation in folded form and in free space, means (26) for photodetection of said radiation thus reflected and means (28) for focusing radiation on said photodetection means.
