Temporal approach to the calculation of the spectral response of optical cavities and filters.
The transfer of a delta-function pulse by parallel-sided optical cavities is considered. It is shown that the spectral characteristics of the cavities can be easily derived by calculating the Fourier transform of this impulse response. This method of calculation appears to be simpler and more intuitive usual standing-wave approach. The method is applied to a number of examples including cavites whose dimensions change with time.
