Xiyuan Lu is an Assistant Research Scientist working primarily on the NIST campus. He received a B.S. in Physics from Nanjing University, China and a Ph.D. in Physics from University of Rochester. His doctoral research focused on developing and characterizing entangled photon sources and heralded single photon sources in high-quality silicon microresonators, and on fabricating silicon carbide micro/nanophotonic devices for optomechanical and nonlinear optical applications. He is now working to develop chip-scale nonlinear photonic devices such as optical parametric oscillators, spectral translators, and entangled photon-pairs sources.

    Two Light-Trapping Techniques Combine for the Best of Both Worlds

    January 3, 2023

    Taming rays of light and bending them to your will is tricky business. Light travels fast and getting a good chunk of it to stay in one place for a long time requires a lot of skillful coaxing. But the benefits of learning how to hold a moonbeam (or, more likely, a laser beam) in your hand, or on a convenient chip, are enormous. Trapping and controlling light on a chip can enable better lasers, sensors that help self-driving cars “see,” the creation of quantum-entangled pairs of photons that can be used for secure communication, and fundamental studies of the basic interactions between light and atoms—just to name a few.

    Enhanced Frequency Doubling Adds to Photonics Toolkit

    The digital age has seen electronics, including computer chips, shrink in size at an amazing rate, with ever tinier chips powering devices like smartphones, laptops and even autonomous drones. In the wake of this progress, another miniature technology has been gaining steam: integrated photonics. Photons, which are the quantum particles of light, have some advantages over electrons, the namesakes of electronics. For some applications, photons offer faster and more accurate information transfer and use less power than electrons. And because on-chip photonics are largely built using the same technology created for the electronics industry, they carry the promise of integrating electronics and photonics on the same chip.
