Refractive index sensing with an air-slot photonic crystal nanocavity.
We investigate an air-slot photonic crystal cavity for high-precision refractive index sensing. The high quality factor approximately 2.6x10(4) of the cavity, along with a strong overlap between the resonant mode and the hollow core region, allows us to achieve an experimental sensitivity of 510nm per refractive index unit (RUI) and a detection limit below 1x10(-5)RUI. The device has a remarkab...
متن کاملAir-mode photonic crystal ring resonator on silicon-on-insulator
In this report, we propose and demonstrate an air-mode photonic crystal ring resonator (PhCRR) on silicon-on-insulator platform. Air mode is utilized to confine the optical field into photonic crystal (PhC) air holes, which is confirmed by the three-dimensional finite-difference time-domain simulation. PhCRR structure is employed to enhance the light-matter interaction through combining the whi...
متن کاملImaging of photonic crystal cavity mode via refractive index sensing
Silicon (Si) based integrated Photonic Crystal (PhC) cavities show great promise for biosensing applications, owing to their high Quality (Q) factor, low mode volume and compatibility with Complementary metal–oxide–semiconductor (CMOS) fabrication. We present the development of a new experimental technique to experimentally determine the sensing properties of PhC cavity mode. It makes use of a ...
متن کاملPhotonic crystal heteroslab-edge microcavity with high quality factor surface mode for index sensing
In this report, we propose a photonic crystal heteroslab-edge microcavity design for optical index sensing, where the high quality Q surface mode is confined by mode-gap effect. By optimizing the barrier region of the microcavity, high Q factor of 6.6 105 is obtained in simulations. Lasing actions with high Q factor and low threshold of 6400 and 0.55 mW are obtained from the real devices. High ...
متن کاملTwo-curve-shaped biosensor using photonic crystal nano-ring resonators
We design a novel nano-ring resonator using two-dimensional photonic crystal (2D-PhC), for bio-sensing applications. The structure of biosensor is created by two-curve-shaped ring resonator which sandwiched by two waveguides. These are configured by removing one row of air holes. The refractive index of sensing hole is changed by binding an analyte. Hence, intensity of the transmission spectrum...
