The scattering parameters of a time-modulated two-coupled-cavity system are obtained using coupled mode theory and verified using the finite-difference time-domain method. We find that a suitably tailored time-modulation of the cavities allows for switching the output on and off. The proposed functionality can be used in direct amplitude modulation of an optical carrier from a frequency-modulated RF message.
