Visible photonic band gap engineering in silicon nitride waveguides
نویسندگان
چکیده
We demonstrate experimentally the tuning of complete photonic band gaps in patterned silicon nitride waveguides. Transmission measurements were performed using an ultrabroadband high-brightness white light laser continuum, extracting extinction ratios as low as 10 in the gap regions. Angle-resolved measurements show the perfect alignment of the gap around the G-J direction. © 2000 American Institute of Physics. @S0003-6951~00!02008-8#

Optical bandgap engineering in nonlinear silicon nitride waveguides.
Silicon nitride is a well-established material for photonic devices and integrated circuits. It displays a broad transparency window spanning from the visible to the mid-IR and waveguides can be manufactured with low losses. An absence of nonlinear multi-photon absorption in the erbium lightwave communications band has enabled various nonlinear optic applications in the past decade. Silicon nit...
متن کاملTantalum(V) nitride inverse opals as photonic structures for visible wavelengths.
The development of materials with a complete photonic band gap at visible wavelengths is believed to have the potential to lead to new control over long-lived emissive excited states, single molecule lasers, and nearly lossless nanoscale waveguides. In this work we move toward that goal with the synthesis of an inverse opal thin film of Ta3N5 produced through atomic layer deposition. The highly...

We demonstrate design, fabrication, and characterization of two-dimensional photonic crystal (PhC) waveguides on a suspended silicon rich nitride (SRN) platform for applications at telecom wavelengths. Simulation results suggest that a 210 nm photonic band gap can be achieved in such PhC structures. We also developed a fabrication process to realize suspended PhC waveguides with a transmission ...

In this research, we have studied the photonic band structure, optical properties and thermal emission spectrum of 2D Silicon photonic crystal with hexagonal structure. The band structure, band gap map and the gap size versus radius have been calculated by plane wave expansion method. The maximum band gap size of TE (TM) polarization and the complete gap size are 51% (20%) and 17% at air hole r...

In this article, we investigate how the photonic band gaps and the variety of band dispersions of photonic crystals can be utilized for various applications and how they further give rise to completely novel optical phenomena. The enhancement of spontaneous emission through coupled cavity waveguides in a one-dimensional silicon nitride photonic microcrystal is investigated. We then present the ...
