Abstract: An optical fiber multi-parameter sensing system and method are provided. The optical fiber multi-parameter sensing system comprises a light source, an optical circulator, a fiber-tip probe sensor and an optical spectrum analyzer, wherein the fiber-tip probe sensor can be placed into an analyte without changing the characteristics of the analyte. The variation of a bulk parameter that is a bulk refractive index of bulk environment around the fiber-tip probe sensor and a surface parameter which is a thickness of surface dielectric layer of the fiber-tip probe sensor can be determined simultaneously by monitoring the changing of resonance intensity and resonance wavelength of a single fiber-tip leaky mode resonance. The sensing system optionally configured such that multiple parameters in the analyte around the fiber-tip probe sensor can be obtained by detecting a single resonance peak.

Abstract: The present disclosure relates to a method of electrically aging a PMOS thin film transistor. The method includes applying a first voltage Vg with an amplitude of A volts to a gate of the PMOS thin film transistor; applying a second voltage Vs with an amplitude of (A?40) to (A?8) volts to a source of the PMOS thin film transistor; and applying a third voltage Vd with an amplitude of (A?80) to (A?16) volts to a drain of the PMOS thin film transistor. Application of the first voltage Vg, the second voltage Vs and the third voltage Vd is maintained for a predetermined time period, and Vd?Vs<0. In this way, reduction of a leakage current of the PMOS thin film transistor is achieved without changing a structural design of the thin film transistor.
