“…Optical gyroscopes are categorized in three types of fiber optic gyroscopes (FOGs), ring laser gyroscopes (RLGs), and optoelectronic gyroscopes 1 , 4 , 5 . The duty of a gyroscope is to determine the angular velocity of a rotating object 1 , 6 – 9 . In fact, optical gyroscopes provide noteworthy features like high speed, high accuracy, and high reliability in optical wavelengths 1 , 4 , 10 – 12 .…”

“…Accordingly, in continue to our ongoing project on optical gyroscopes 6 – 9 , we provide a novel hybrid structure to be used as SPP-based integrable optical gyroscope which solves the discussed drawbacks of conventional devices. The idea of using SPPs for measuring angular velocity is established based on the plasmonics waves’ characteristics, including high sensitivity and sub-wavelength confinement (small dimensions).…”

This paper presents an optoplasmonic gyroscope that employs a novel bent-hybrid structure, and works double-sided. The proposed device is integrable without moving parts, and simply has a robust configuration. The detection mechanism is based on surface plasmon polaritons (SPPs), and the sensor consists of a laser, a bent-metal layer, and a photo-detector (PD). Based on the simulations, the proposed gyroscope provides significant characteristics of a measurement range of ± 45000°/s, an optical sensitivity of 6.025 µ/(°/s), a total sensitivity of 2.41 µA/W(°/s), an ultra-high resolution ability of 16.598 µ°/s, and an accuracy of 99.999%. The dimensions are 5 × 5 × 5 µm3, and the measurement time is 1 ms. The operational wavelength is at visible range of λ = 630 nm. Additionally, the effects of various parameters, including metal material, metal thickness, and laser wavelength, on the gyroscope performance are comprehensively studied.
