Abstract
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.
