This paper introduces a novel micro-opto-electro-mechanical-systems accelerometer that leverages a tunable all-dielectric meta-material. The device operates by modulating the wavelength of incident light-wave. The utilized metamaterial takes advantage of highly tunable ultra-sharp Fano resonance peaks to create a high-performance accelerometer, offering enhanced sensitivity and resolution. Simulation results indicate the functional attributes of the proposed sensor: a mechanical sensitivity of 0.13 nm/g, a linear measurement range spanning ±38.4 g, and an overall sensitivity of 1.17 nm/g. These characteristics render the device applicable across a broad spectrum of uses, from consumer electronics to inertial navigation.

In the present paper, we propose a new Photonic Crystal Fiber (PCF) design and analyze the contribution of geometrical parameters to the photonic crystal fibers dispersion and effective refractive index. The proposed design is validated using the 3-D finite-difference time-domain technique. According to the results of this paper, by increasing the radius of the core, the dispersion coefficient sign changes from positive to negative. For a radius of 0.5 µm at wavelengths above 1600 nm, the dispersion is close to zero. For a core refractive index greater than 1.47, the dispersion will be zero. By increasing the core refractive index, the zero-dispersion wavelength is increased. Manuscript profile
