Tunable Optical Filters Using Compound Ring Resonators for DWDM [PDF]
, 2003 The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the same optical path between the ...

Dynamically tunable terahertz metamaterial sensor based on metal–graphene hybrid structural unit
AIP Advances, 2022 By verifying the electromagnetic response characteristics of graphene in the low terahertz (THz) band, a terahertz metamaterial sensor is proposed. The unit cell of the metamaterial sensor is a split ring resonator nested square ring resonator. The split

Topological resonances in a Möbius ring resonator
Communications Physics, 2023 AbstractA Möbius strip, fascinating for its unique topological property of being a one-side nonorientable surface, has inspired mathematicians, physicists, engineers, and artists for many centuries. In a coherent system, coherent waves on the nonorientable surfaces reveal rich topological dynamics due to the interplay of coherence and topology. Here we
