Abstract :
We propose and design a novel photo-elastic modulator (PEM) utilizing quasi-1D phononic crystal (PnC) cavity. The structure can support an acoustic cavity mode with a Q-factor as high as 9.5×104. This enables efficient optical modulation by a factor of 2.5 compared to commonly-used PEMs.
