Superprism Effect in Thin Film Fabry-Perot Filter

摘要：

For the sake of achieving remarkable superprism effect,we investigate in thin film Fabry-Perot filter which possess drastic change in phase and large group delay around wavelength of peak transmittance. The group delay and spatial dispersion shift are simulated numerically; while the device is fabricated and tested with the maximum spatial separation shift reach to 65μm. We also analyze Gaussian beam propagating in the device to give the interpretation of the spot splitting phenomenon in this experiment. Compared with the traditional prism, the total thickness of our structure is only 3. 3μm, and shows a very large deflection angle about 30°/nm.
