Optical wavelength conversion over an ultrawide spectral range based on an intermodal transition induced by dynamic tuning of a double heterostructure photonic crystal cavity is numerically demonstrated. Exploiting the inherently large spectral separation between the eigenmodes and the field symmetries to suppress multiple mode couplings, a normalized wavelength shift of about 25% with feasible index tuning is achievable by coupling only two resonances.
基于双异质结构光子晶体腔的动态调谐诱导的模间跃迁实现了超宽光谱范围内的光波长转换，数值上得到了验证。利用本征模之间的固有大光谱分离和场对称性来抑制多模耦合，通过仅耦合两个共振，可实现约 25%的归一化波长移动，且具有可行的折射率调谐能力。
