| Abstract: | The theoretical analysis of the phase modulation with respect to the symmetrical metal-clad waveguide oscillating biochemical sensor is presented and an experiment scheme based on the Mach-Zehnder interference is proposed.It is demonstrated that the phase modulation is superior to the intensity modulation for the capability of a higher sensitivity and a larger detection range of the refractive index variation. |

| Keywords: | symmetric metal-cladding waveguide ultrahigh-order modes phase modulation biochemical sensor sensitivity |
