We demonstrate on-chip absorption spectroscopy using silicon microring resonators with integrated microfluidic channels. Using a 40 mum radius resonator with Q>15,000 we show absorption spectra of less than 90 nL volumes of water and methanol from 1460 nm-1560 nm.
We present a multi-layer waveguide that can confine light in low refractive index layers. M-line measurement verified our simulation results. This structure can be used for silicon light emission device because free-carrier losses are avoided.
We describe, fabricate and demonstrate multi-slotted silicon nanophotonic waveguides, comprised of four low index slots etched longitudinally along the waveguide. The computed modal profiles are well described by supermode theory. We have measured the group index of refraction of the waveguide in the TE and TM polarizations.
In this paper we present our work towards the development of nanoscale optofluidic sensor arrays (NOSAs) for Dengue virus detection. Our approach is based on the use of optically resonant devices whose resonant wavelength is shifted due to a local change in refractive index caused by a positive binding event between a surface bound molecule and it solution phase target. A special two stage micro-/nanofluidics...
We detect acetylene gas on a silicon chip using photonic microcavities and a chip-scale gas cell. We measure refractive index differences as small as 10-4 between air and acetylene at varying pressures in the near-IR.
