Abstract
A new four-channel demultiplexer of single photons is proposed, in which four microresonators are utilized to link the four drop waveguides and the bus waveguide. By adjusting the system parameters, the crosstalk effect of the multiple channel frequencies is suppressed, and multiple peak frequencies with high drop efficiencies in these output ports are achieved. As the 2 × 2 model is scalable, the proposed structure can provide potential applications in designing scalable optical devices.
