Abstract
We propose and experimentally demonstrate a surface plasmon resonance sensor based on D-shaped single mode silica optical fiber and Indium Tin Oxide (ITO) that operate in the infrared wavelength region. The experimental result revealed that, a sensor fabricated with 0.6dB insertion loss and coated with 120nm thickness ITO layer presented a resonance in the wavelength range of 1200nm - 1400nm, and a refractive index sensitivity of 1409.34 nm/RIU with R-squared 0.99 for the range 1.33 - 1.42 RIU. We investigated also the effects of the polishing depth of D-shaped fiber and the thickness of ITO film on the performance of the sensor sensitivity. Both the experimental result and the COMSOL numerical simulation result indicate that when the thickness of ITO film increases, the resonance wavelength shift to the longer wavelength. However, in order to ensure that the sensor performance is not affected, the polishing depth should be appropriately reduced when the thickness of ITO film is increases; conversely, when the thickness of ITO film decreases, the polishing depth should be increased.
