Latest Patents

Cheng holds a patent for a "Wideband acousto-optic modulator/isolator in integrated photonics." This acousto-optic device employs strong interband coupling in a multi-mode, spiral-shaped optomechanical waveguide. The device includes multiple interdigitated transducers that produce phonons, which are directed to the optomechanical waveguide at an angle. By confining the produced phonons to the optomechanical waveguide, using phonon confining elements and/or a suspended structure, the interband coupling is increased. Through the use of spatial mode multiplexers at either end of the optomechanical waveguide to block or pass different spatial optical modes, one can create an acousto-optic modulator or an optical isolator. Cheng's innovative approach has led to advancements in the efficiency and functionality of acousto-optic devices.
