Experimental demonstration of an all-optical analogue to the superradiance effect in an on-chip photonic crystal resonator system

We show that an all-optical analogue to the Dicke superradiance effect can be observed in on-chip photonic crystal resonator systems where two resonators are separated by a distance much longer than the wavelength of the optical resonators' resonance. In addition, we provide the experimental observation of structural tuning of the superradiance effect in micron-sized optical resonators in a silicon photonic crystal slab.
