Paper Abstract

We will summarize the progress made by us on the efficient conversion of phonon polariton waves from input optical waves at lower frequencies to output optical waves at higher frequencies. The efficient conversion is made possible by utilizing waveguide structures and giant second-order nonlinearities. Such giant nonlinearities originate from huge enhancements due to phonon polariton resonances. We have calculated the highest conversion efficiencies from the phonon polariton waves to the output optical waves for a variety of semiconductor materials. Our results show that such a novel scheme can be used to efficiently remove the energies carried by the phonons.
