Mid-infrared photonic crystal cavities in silicon.
We demonstrate the design, fabrication, and characterization of silicon photonic crystal cavities realized in a silicon on insulator (SOI) platform, operating at a wavelength of 4.4 μm with a quality factor of 13,600. Cavity modes are imaged using the technique of scanning resonant scattering microscopy. To the best of our knowledge, this is the first demonstration of photonic devices fabricate...
متن کاملPhotonic crystal cavities in silicon dioxide
One dimensional nanobeam photonic crystal cavities fabricated in silicon dioxide are considered in both simulation and experiment. Quality factors of over 104 are found via simulation, while quality factors of over 5 103 are found in experiment, for cavities with mode volumes of 2.0 /n 3 and in the visible wavelength range 600–716 nm. The dependences of the cavity quality factor and mode volume...
متن کاملOptical bistability and free carrier dynamics in graphene–silicon photonic crystal cavities
We introduce graphene–silicon hybrid nonlinear devices operating at a few femtojoule cavity circulating energies, including: (1) dualand single-cavity optical bistability; (2) detailed and broadband switching dynamics, and (3) free-carrier and thermal effects in regenerative oscillations. Sub-wavelength nanostructures confine light in a single mode silicon resonator with high Q/V ratio, enablin...
متن کاملCoupled fiber taper extraction of 1.53 microm photoluminescence from erbium doped silicon nitride photonic crystal cavities.
Optical fiber tapers are used to collect photoluminescence emission at approximately 1.5 microm from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. In the experiment, photoluminescence collection via one arm of the fiber taper is enhanced 2.5 times relative to free space collection, corresponding to a net collection efficiency of 4%. Theoretically, the collecti...
متن کاملPhotonic crystal cavities in cubic (3C) polytype silicon carbide films.
We present the design, fabrication, and characterization of high quality factor (Q ~10(3)) and small mode volume (V ~0.75 (λ/n)(3)) planar photonic crystal cavities from cubic (3C) thin films (thickness ~200 nm) of silicon carbide (SiC) grown epitaxially on a silicon substrate. We demonstrate cavity resonances across the telecommunications band, with wavelengths from 1.25 - 1.6 μm. Finally, we ...
