Publication number: 20220206361Abstract: Photonic controlled-phase gates that include a dipole emitter chirally coupled to a plurality of photonic qubit pairs in a waveguide are disclosed herein. Each photonic qubit pair includes a two-qubit state |xy, wherein the two-qubit state |xy comprises a combination of single-qubit states |0 and |1, and may be |00, |01, |10, and |11. The dipole emitter is configured to interact with the single-qubit state |0 to impose a ? phase shift, and the dipole emitter interacts with states |00, |01, and |10 to impose the ? phase shift.Type: ApplicationFiled: December 23, 2021Publication date: June 30, 2022Applicant: Washington UniversityInventors: Jung-Tsung Shen, Yao Zhou, Zihao Chen

Patent number: 10833469Abstract: A photonic molecule laser is described that includes a photonic molecule waveguide coupled to a photonic molecule seeding source configured to deliver a plurality of photonic molecules. The photonic molecule waveguide includes a second dopant maintained at a population inverted state with an energy level transition corresponding to a second frequency that is an N-fold multiple of a first frequency and amplifies the number of photonic molecules via stimulated emission. The photonic molecule seeding source includes a waveguide with a first dopant maintained at a population inverted state with an energy level transition corresponding to the first frequency. A pump source is coupled to the waveguide configured to deliver a first frequency laser pulse with pulse coherence time less than the photonic molecules correlation time. Each photonic molecule includes a threshold bound state of N first frequency photons, and each photonic molecule has the second frequency.Type: GrantFiled: October 12, 2018Date of Patent: November 10, 2020Assignee: Washington UniversityInventors: Jung-Tsung Shen, Lihong Wang

Publication number: 20150168645Abstract: Embodiments provide metamaterials having an enhanced nonlinear response to light. The metamaterials are artificially manufactured materials having a nonlinear response to light greater than that typically found in naturally occurring materials. A two-dimensional periodic metal-dielectric array can be mathematically mapped as an effective uniform dielectric slab with enhanced optical nonlinearity. The enhanced nonlinearity is controlled by the geometry of the array. Further, the configuration of the array can be applied to form three-dimensional structures having an enhanced nonlinear response to light.Type: ApplicationFiled: February 4, 2015Publication date: June 18, 2015Inventors: Jung-Tsung Shen, Daniel Ironside
