基于单向相干完全吸收的光子晶格非互易传输

Non-reciprocal transmission in photonic lattices based on unidirectional coherent perfect absorption

Stefano Longhi

摘要:

利用单向相干完全吸收的思想,提出了一种在调制线性纯无源光晶格中实现离散光非对称(单向)传输的方法。该系统由耦合谐振器或波导的线性光子晶格组成,侧面耦合到一系列有损耗元件,其中光在以一种方式传播时可以避免占据耗散位置,但在相反的方向上则不会。非互易性要求调制谐振器/波导参数,实现具有非互易行为的耗散光学Aharonov-Bohm二极管。

英文摘要:

A method for realizing asymmetric (one-way) transmission of discretized light in modulated, linear and purely passive optical lattices is suggested, which exploits the idea of unidirectional coherent perfect absorption. The system consists of a linear photonic lattice of coupled resonators or waveguides, side coupled to a chain of lossy elements, in which light can avoid the occupation of the dissipative sites when propagating in one way, but not in the opposite one. Non-reciprocity requires modulation of the resonator/waveguide parameters, realizing a dissipative optical Aharonov-Bohm diode with non-reciprocal behavior.
