ESE Fall Colloquium – “Harnessing Piezoelectricity in Novel Microsystems for Classical and Quantum Information Processing”
December 16, 2021 at 11:00 AM - 12:00 PM
Piezoelectricity is the intrinsic coupling between electric fields and strains in materials. While piezoelectric sensors, actuators, and RF filters are ubiquitous and important components of existing microsystems, their potential is still largely underutilized in many application spaces. In this talk, I will discuss the physics, engineering, and applications of two novel classes of piezoelectrically enabled microsystems developed by the MEMS-Enabled Quantum Photonics group at Sandia National Labs: (1) piezoelectrically modulated photonic, phononic, and optomechanical integrated circuits and 2) piezoelectric-semiconductor hybrids for all-acoustic radio frequency signal processing and acoustoelectrically enhanced optomechanics. I will discuss these systems in detail and show how they are being used to make significant advances in both classical and quantum information processing applications.
Distinguished Member of the Technical Staff and Group Leader, MEMS-Enabled Quantum Photonics
Matt Eichenfield received his PhD in physics at Caltech in 2010, where his thesis focused on developing photonic and phononic crystals—so-called optomechanical crystals—that produce extremely strong and tailorable light-matter interactions. He was subsequently the Kavli Nanoscience Institute Prize Postdoctoral Fellow at Caltech before starting at Sandia National Labs as a Harry S. Truman Fellow in 2011. At Sandia, he has built the MEMS-Enabled Quantum Photonics group from the ground up, which focuses on developing MEMS platforms that harness light-matter interactions for applications in classical and quantum information processing, as well as other MEMS platforms for applications such sensors for extreme environments, as well as acoustic radio-frequency signal processing.
