<span>The phenomena of surface plasmon resonance (SPR) has been observed. SPR is reflectance <span>curve as a function of incident angle in Kretschmann configuration. Surface plasmon is elec<span>tromagnetic waves propagation in the interface area between metal and dielectric that can be <span>excited by using attenuated total reflection (ATR) method. The result of experiment explains <span>that the SPR angle on the thin film system of the prism/silver 1 and the prism/silver 2 is (42.8<br /><span>± 0,05)º with the reflectance value 0.32 and 0.44 respectively. On the prism/silver/silver <span>nanoparticle system, it is obtained that SPR angle value is (4,29 ± 0,05) with the reflectance <span>value 0.29 for the silver 1 and 0.31 for the silver 2. After the thin film system is added with <span>40% of formalin, SPR angle becomes (43,0 ± 0,05)º with the reflectance value 0.44. Then, af<span>ter the thin film system is added with 100% of formalin, SPR angle becomes (43,2 ± 0,05)º<br /><span>with the reflectance value 0.4. The shifting SPR angle shows that SPR have capability as <span>formalin sensor.</span></span></span></span></span></span></span></span></span></span></span><br /></span>

Mechanical Optimization

Mechanical optimization has been done on the surface plasmon resonance (SPR) homemade. At set-up, angle scanning comes a small resolution to detect changes in the thickness of the thin film or refractive index of the sample. The mechanical drive has a function to rotate the prism and detector. Torsional Spring-Loaded Gear Antibacklash is used to improve the accuracy of the mechanical drive. The stepper motor is used to rotate the mechanical drive automatically. The built system has successfully increased the resolution of the prism rotation angle by 0.01°. The test using the blank prism indicates the angle of Total Internal Reflection occurs at an incident angle of 41.80 °. The SPR phenomenon was observed in a thin layer of gold deposited on the prism using a vacuum evaporator. The observed SPR angles on samples A, B, C, D, E, F, G, H and I were 45.02°, 45.05°, 46.30°, 44.48°, 44.70°, 45.49°, 45.52°, 45.66°, and 44.44°, respectively. The SPR angle change shows the difference in the thickness of the gold thin film.

Optical Reflectance

We demonstrate magnetic control of optical reflectance with no ferromagnetic material via combining the Faraday rotation and the surface plasmon resonance (SPR) in a Kretschman configuration under magnetic fields < 0.5 T. The SPR produces the polarization sensitive reflectance from the Au or Ag thin film coated on a N-BK7 prism in which the Faraday rotation occurs. The gold (Au) or silver (Ag) metal film as a plasmonic film somewhat acts as an incident angle-dependent reflection polarizer that can sensitively sense the polarization change induced by the Faraday rotation that occurs in a prism. We find that combination of Faraday rotation and the surface plasmon can induce a significant magnetic modulation of reflectance normalized with respect to that obtained with no magnetic fields at a specific incident angle of light. The magnetic control of optical reflectance presented may find an application in polarizer-free photonic devices with no ferromagnetic material for magneto-optical modulation.
