The realisation process and the preliminary tests on the performances of an integrated Mach-Zehnder Interferometer on LiNbO3 (Lithium Niobate) substrate is presented. The microsystem has been obtained by using medium mass Ion Implantation on X-cut Lithium Niobate crystals. The interferometer is formed by integrated optical channel waveguides; the phase shift between the two optical paths has been obtained, without moving parts, by applying a suitable electric field. The whole device is 60mm long, has a 0.5x1mm2 cross section and weights a few grams. The power consumption is in the milliwatt range. In the present work results obtained in the spectral window (0.4μm-1.1μm) will be presented. The performance of the device, evaluated on standard radiation sources, demonstrates that a spectral resolution better than 0.3nm can be obtained on 400nm spectral windows. The Micro-interferometer has been …
