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 silicon waveguides and devices in hyperuniform disordered photonic solids. Our results demonstrate the ability of disordered photonic bandgap materials to serve as a platform for optical integrated circuits.
We report preliminary results for silicon waveguides and devices in hyperuniform disordered photonic solids. Temperature sensitivity of resonant defects is more than 500 times lower than that of the standard silicon microring resonators.
We demonstrate the strongest effect of dark-soliton attraction in a new type of nonlocal thermal self-defocusing nonlinear media (m-cresol/nylon solutions). Formation of spatial shock waves is also observed with only mW power.
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 demonstrate stable beam self-trapping in soft-matter systems with artificial saturable self-focusing nonlinearities. Our experiments reveal optical beam interactions that can vary from attractive to repulsive as well as an energy exchange.
We report a new type of Kerr-like nonlinear media (m-cresol/nylon solutions) exhibiting a giant tunable self-defocusing nonlinearity. Their nonlinear response can be enhanced dramatically by increasing the nylon concentration and is verified to be isotropic.
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.
We report the first experimental demonstration of photonic bandgaps (PBGs) in 2D hyperuniform disordered materials and show that is possible to obtain isotropic, disordered, photonic materials of arbitrary size with complete PBGs.
By the advantage of a metastable state, amplification without inversion has been exhibited with the remarkable characteristic that the population distribution of the upper state for the amplified transition is produced by the coupling coherent laser rather than direct incoherent pumping. We proposed two similar models which involve light amplification arising from either coherence or stimulated Raman...
