Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and Purdue University demonstrated a hybrid approach to on-chip acousto-optic modulation by combining piezoelectric aluminium nitride technology with ultralow-loss silicon nitride integrated photonics.
The hybrid circuit allows wideband actuation on photonic waveguides with ultralow electrical power. A key feature is that it maintains the ultralow loss of silicon nitride circuits. Silicon nitride has emerged as a leading material for chip-scale, microresonator-based optical frequency combs (microcombs).
The researchers integrated microelectromechanical systems (MEMS) transducers made of aluminum nitride with a silicon photonic wafer to modulate…READ MORE
