Fundamental limits to signal integrity in nonlinear parametric optical circulators
Ian A. D. Williamson, Zheng Wang
We characterize the response of a parametric nonlinear optical circulator to realistic signals that have finite bandwidths. Our results show that intermodulation distortion (IMD),…
A silicon Brillouin laser
Nils T. Otterstrom, Ryan O. Behunin, Eric A. Kittlaus +2
Brillouin laser oscillators offer powerful and flexible dynamics as the basis for mode-locked lasers, microwave oscillators, and optical gyroscopes in a variety of optical systems.…
Extraordinary wavelength reduction in terahertz graphene-cladded photonic crystal slabs
Ian A. D. Williamson, S. Hossein Mousavi, Zheng Wang
Photonic crystal slabs have been widely used in nanophotonics for light confinement, dispersion engineering, nonlinearity enhancement, and other unusual effects arising from their…
Kinetic inductance driven nanoscale 2D and 3D THz transmission lines
S. Hossein Mousavi, Ian A. D. Williamson, Zheng Wang
We examine the unusual dispersion and attenuation of transverse electromagnetic waves in the few-THz regime on nanoscale graphene and copper transmission lines. Conventionally, suc…
Control of coherent information via on chip photonic-phononic emitter-receivers
Heedeuk Shin, Jonathan A. Cox, Robert Jarecki +3
Rapid progress in silicon photonics has fostered numerous chip-scale sensing, computing, and signal processing technologies. However, many crucial filtering and signal delay operat…
Reflection-Free One-Way Edge Modes in a Gyromagnetic Photonic Crystal
Zheng Wang, Y. D. Chong, John D. Joannopoulos +1
We point out that electromagnetic one-way edge modes analogous to quantum Hall edge states, originally predicted by Raghu and Haldane in 2D gyroelectric photonic crystals possessin…
