Abstract
A multifunctional parametric device using an optical material in which permittivity is spatiotemporally modulated according to the present invention may be used as a frequency converter and oscillator according to a design characteristic. Since a converted and oscillated frequency is determined according to a modulation frequency of a thin slab of which permittivity is spatiotemporally modulated, a user is capable of actively determining a frequency modulation and oscillation characteristic using the parametric device.
