Circuits for light in holographically defined photonic-band-gap materials

摘要: We present a theoretical roadmap for three-dimensional optical waveguide networks in holographically defined, diamondlike photonic band gap (PBG) materials. A fully 3D network is demonstrated through broadband $(100--200\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$, single-mode waveguiding air, coupled with sharp bends three dimensions minimal backscattering. Optimal waveguides the in-plane $x$ and $y$ directions are shown to exhibit nearly $250\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ of bandwidth light wavelengths near $1.5\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$. Vertical channels formed by introducing air defects zigzag pattern. Realization these circuit designs may be achieved combination direct laser writing within defined photoresist subsequent replication microchip template high refractive index semiconductor such as silicon.
