We report experimental and simulation results for silicon waveguides and resonant cavities in hyperuniform disordered photonic solids. Our results demonstrate the ability of disordered photonic bandgap materials to serve as a platform for silicon photonics.
We report experimental and simulation results for low-loss wave-guiding in Si-based hyperuniform disordered photonic bandgap materials at infrared wavelengths. These results pave the way for deploying disordered photonic solids in integrated photonic circuits.
A new designer dielectric metamaterial featuring an isotropic photonic bandgap at 1550 nm wavelength designed as a finite thickness, 220 nm thick 2d slab, is fabricated in a CMOS-compatible silicon-on-insulator process. This “hyperuniform disordered solid” (HUDS) is neither crystalline nor quasicrystalline.
We show theoretically and experimentally that photonic lattices constructed from random components residing on a ring in momentum space are amorphous, yet they exhibit a bandgap, and support linear and nonlinear defect-state guidance.
We demonstrate for the first time stable self-trapping and self-induced transparency of light propagating in colloidal nano-suspensions with negative polarizabilities. Comparing to “polystyrene-water”-colloidal systems with positive polarizabilities, a fivefold increase in transmission ratio is achieved.
We report the first experimental demonstration of guiding, bending, filtering, and splitting of EM wave in 2D disordered PBG materials, along arbitrarily curved paths, around sharp bends of arbitrary angles, and through Y shape junctions.
