| description | We propose a Kretschmann-based nonlinear plasmonic sensor with a gold thin film deposited on a glass prism. Visible and mid-infrared signals are generated in this configuration through the nonlinear processes of sum- and difference-frequency generation, respectively. The calculated maximum sensitivity and figure of merit of our sum-frequency-based sensor is an order of magnitude higher than that of a traditional Kretschmann-based sensor in the visible range. Our difference-frequency-based sensor has a maximum sensitivity of <inline-formula> <tex-math notation="LaTeX">$1.0\times 10^{6}$</tex-math></inline-formula> <inline-formula><tex-math notation="LaTeX"> $\text{nm/RIU}$</tex-math></inline-formula> in air at 4.29 <inline-formula><tex-math notation="LaTeX">$\mu\text{m}$ </tex-math></inline-formula>, which is three orders of magnitude higher than that of existing devices in the mid-infrared range, with its maximum figure of merit almost two orders of magnitude higher than the alternatives. By comparison, the calculated sensitivity for operation in water for both sum- and difference-frequency is about half that in air. We, thus, demonstrate significant gains in the sensitivity of the well-known Kretschmann-based plasmonic sensor over a wide wavelength range, without modifying the physical sensor, but by exploiting and simply taping the nonlinear optical properties of the system. |
