Figure | Chiral EP enhanced electro-optic tuning and low energy directional optical interconnects. a. Schematics of the chiral microring resonator (MRR), with lithographically defined low loss asymmetric Mie scatterer (Inset), which mediates asymmetric coupling between clockwise (CW) and counterclockwise (CCW) modes. Local nano-heater tunes inter-scatter phase, leading to the tunable asymmetric coupling strength in the device. b. 3-dimentional imaging laser microscope captured image of the non-Hermitian photonic modulation coupled to add-drop type microring resonator, manufactured through a foundry wafer run. c. Exemplary application scenario of the chiral electro-optic response enabled unidirectional data flow between transmitting electronic integrated circuits (EICs) and receiving EICs. In conventional MRMs, duplicated circuit topologies for transmitting and receiving terminals are required to avoid crosstalk (grey).
