Abstract

A novel special waveguide sensor, which is very sensitive to magnetic field, is proposed. This novel special wave guide is combined by two kinds material, YIG polymer and Bi:YIG polymer. The two beam lights counter-propagating in this kind of waveguide can generate large nonreciprocal phase shift. We designed the sensor structure, simulated the propagated characteristic of the structure. Based on the simulations, we concluded that waveguide with the core divided by two half circles can improve the sensitive to the magnetic field which is parallel to the interface of the two semicircles. We design a Sagnac interference demonstration with the light wavelength of 1550 nm, two difference-resonant loops. This sensor with 0.51pTesla-level sensitivity can be used in ultra-low magnetic field detection.
