Title: Innovations of Inventor Wenjun Qiu
Introduction
Wenjun Qiu is a prominent inventor based in Chicago, IL (US), known for his groundbreaking contributions to the fields of opto-acoustic devices and transparent display technologies. With a total of 6 patents, his work has significantly advanced the understanding and application of hybrid phononic-photonic waveguide structures.
Latest Patents
One of his latest patents is the "Guided wave opto-acoustic device." This invention relates to various hybrid phononic-photonic waveguide structures that can exhibit nonlinear behavior associated with traveling-wave forward stimulated Brillouin scattering (forward-SBS). The structures can simultaneously guide photons and phonons in a suspended membrane, eliminating substrate pathways that typically cause loss of phonons. This innovation achieves forward-SBS nonlinear susceptibilities approximately 3000 times greater than conventional waveguide systems. The strong phonon-photon coupling opens up potential applications in radiofrequency (RF) and photonic signal processing across a wide bandwidth, from 100 MHz to 50 GHz or more.
Another significant patent is for "Methods and apparatus for transparent display using scattering nanoparticles." This technology enables the creation of transparent displays for various applications, including heads-up displays for vehicles and eyeglasses. Unlike traditional organic light-emitting diode displays, which are often expensive and opaque, Qiu's transparent displays utilize resonant nanoparticles to scatter visible light. This results in a display that is both energy-efficient and practically transparent under ambient light, making it scalable and viewable over wide angular ranges.
