从理论上研究了利用异质结中的光隧穿机制构造紧凑高效的全光二极管的可行性。利用一维光子晶体（1D PC）和有耗金属薄膜异质结的光隧穿特性，不仅可以充分利用金属材料的大非线性介电常数，而且可以构造出具有强非互易电场分布的异质结结构。最后，我们设计了一种一维PC-金属异质结复合结构，在工作波长557.2nm处实现了最佳的单向光传输，其透射对比度为0.984，透射率为42%，工作光功率为0.93GW / cm（2）。(C)2010年美国光学学会
We theoretically investigate the feasibility of constructing compact and highly efficient all-optical diodes (AODs) based on light tunneling mechanism in heterostructures. Due to light tunneling behaviors in heterostructures with one-dimensional photonic crystals (1D PC) and lossy metallic film, not only very large nonlinear permittivity of metal can be utilized sufficiently but also the structures with strongly nonreciprocal electric field distributions can be constructed. Finally we design a composite structure consisting of 1D PC-metal heterostructures to achieve the optimal unidirectional light transmission with 0.984 transmission contrasts, 42% transmission and 0.93GW / cm(2) operating light power at working wavelength 557.2nm.
