We investigate the physical origin of energy transfer from an incident light with frequency ω to a resonant mode via a linear photonic crystal microcavity. By delicate design of the resonant structure, it is found that the energy conversion efficiency can be greatly improved near the frequency of the incident light. In this way, we can precisely control the frequency of the output light, which is very important for frequency conversion in laser emitting devices and other fields. We also study the dynamic evolvement process in the time domain, and the simulation results show good agreement with the theoretical predictions.
