Designing for beam propagation in periodic and nonperiodic photonic nanostructures: Extended Hamiltonian method
beam propagation nonperiodic photonic nanostructures Extended Hamiltonian method
2015/8/11
We use Hamiltonian optics to design and analyze beam propagation in two-dimensional (2D) periodic structures with slowly varying nonuniformities. We extend a conventional Hamiltonian method, adding eq...

Photonic bandgap (PBG) waveguide microcavities with tightly confined resonant optical modes have been designed,fabricated using high-dielectric-contrast GaAs/AlxOy III–V compound semiconductor s...
Design of three-dimensional photonic crystals at submicron lengthscales
three-dimensional photonic crystals submicron lengthscales
2015/8/12
We present a new class of periodic dielectric structures designed specifically to be amenable for fabrication at submicron lengthscales. The structures give rise to a sizable 3D photonic band gap and ...
