摘要
We propose a nonreciprocal optical add-drop multiplexer with silicon waveguide, which is realized by grating assisted coupler employing magneto-optical nonceciprocal phase shift. This device can achieve different adding or dropping peak wavelengths when light is launched in the forward-directed and backward-directed propagation. The calculation results show that the shift of the different dropping peak wavelengths is up to 0.7 nm. Also, we demonstrate its applications for narrowband optical isolators and circulators. This work demonstrates that on-chip nonreciprocal optical add-drop multiplexers and optical isolations can be implemented with the proposed device, which has promising applications for optical communication systems and photonic integrated devices.
