Abstract An apparatus ( 10 ) and method for dynamic frequency control of a photonic band gap crystal includes an acoustic band gap crystal ( 12 ) having a defect site ( 14 ), a photonic band gap crystal ( 20 ) in the defect site of the acoustic band gap crystal ( 12 ), and a sound wave generator ( 40 ) coupled to the acoustic band gap crystal ( 12 ). Consequently, acoustic waves in the acoustic band gap crystal ( 12 ) can be used to controllably alter transmission properties of the photonic band gap crystal ( 20 ) and thereby modulate the transmission of electromagnetic radiation through the photonic band gap crystal ( 20 ). Acoustic waves in the acoustic band gap crystal ( 12 ) can squeeze the photonic band gap crystal ( 20 ) to change its properties, including one or more of lattice constant, symmetry, and optical refractive index contrast.
