Novel Design of a Micro Gyroscope Based Birefringence Measurement for Sensor Applications


Article Preview

. We propose a new concept of a micro gyroscope which is made by a nonlinear micro ring resonator (i.e. 5-10 microns). The nonlinear behavior of polarized light known as polarization mode dispersion in the micro ring device is introduced by material birefringence (i.e. refractive index), which is described. In practice the measurement of polarization mode dispersion can be performed by projecting the output light into a polarizing beam splitter and detectors, where the change in phase is occurred, and then the birefringence is calculated. In addition, the property of the two orthogonal components (i.e. horizontal (H) and vertical (V) components) can be formed the photon entanglement. Which means the entangled photon can be generated, where the state timing walk-off can also be measured and compensated. The design of micro gyroscope is now capable to reduce the device scale in the micron regime to meet more possible applications such as for the measurement of temperature, pressure, and force based on birefringence sensor, which will be discussed in details.
