Experimental demonstration of induced-transparency based on a novel resonator system

We experimentally demonstrate that coupled-resonator-induced-transparency (CRIT) phenomenon results from classical destructive interference whose spectrum has a narrow transparency peak with low group velocity. In this work, a CRIT resonance with a quality factor of 0.72×105 is demonstrated with the same cavity sizes. The through and drop transmission spectra are reconciled well with each other which are in good agreement with the theoretical analysis. Simultaneously, the resonant wavelength can be controlled by changing the temperature.
