This supplementary file is consisted of 3 excel spreadsheets, and gives the detailed theoretical and experimental results of an Fiber Bragg grating (FBG) biaxial tilt sensor. FBG bialxial tilt sensors used to use two optical fibers and four FBGs to measure inclination in two perpendicular directions, whereas here we have demonstrated one using one optical fiber and two FBGs. The inclination along the direction of the fiber (axial direction) can be distinguished by the difference of the resonant wavelengths of the two FBGs, and the inclination in the transverse direction distinguished by the average of the resonant wavelengths of the two FBG. In the experiments, from -50° to 50° in the axial direction, the difference changed linearly with inclination, R2=0.998, and the sensitivity was 1.1pm/°; from 20° to 70° in the transverse direction, the average changed linearly with inclination, R2=0.902, and the sensitivity was 4.5pm/°.

There are 501 rows and 36 columns; each represents a wavelength; 1-501 rows correspond to the wavelength of 400-900 nm; each column corresponds to a different receiving angle. When the incident angle is different, the receiving angle of each column is different. The definition of incident angle: the angle between incident angle and plane normal. The definition of receiving angle definition: the angle between receiving angle and plane normal, if receiving angle and incident angle are on the same side of normal, then receiving angle is negative, and receiving angle and incident angle are on both sides of normal.

We have numerically studied the quasi pulse evaluation in a nonlinear metal-dielectric-metal (MDM) plasmonic nanoresonator at telecom wavelength. In this system a MDM waveguide, vertically coupled to stub filled with nonlinear chalcogenide glasses to make a nonlinear plasmonic nanoresonator (NPNR). NPNR shows two kinds of optical bistability i.e. S-type and Z-type. The effect of S-type and Z-type bistability on the Gaussian input pulse is studied numerically and showed that the output pulses are square pulse for S-type and nearly dark soliton shape for Z-type pulse if the peak input intensity larger than critical intensity. The output shape of pulse is strongly depending on the input peak power of pulse so such signal processing refers to all optical self-signal processing.

These data are the experimental data from Fig. 3 to Fig. 6.
