Abstract
Section titled āAbstractāWe investigate the coexisting of two-mode and three-mode bunching in the intensity noise correlation by generating multi-order fluorescence from pseudo-thermal light source at low temperature using the Nitrogen-vacancy center in diamond. The coexisting mechanism suggests that three-mode bunching is overlapped with two-mode bunching via path indistinguishability, which can be further decomposed into multiple lower order correlation through path distinguishable offset. Moreover, the contribution from two-mode bunching in third order intensity noise correlation function is twice with respect to three-mode bunching. We demonstrate the interference among two- and three-mode bunching by controlling the time offset and dressing the slow light to realize multi-channel optical routing. Our experimental results suggest the advance technique of peak division and channel equalization ratio of about 95%, applicable to all multi-channel optical routing. The switching speed between two channels is about 20 ns.
