چکیده
|
Aiming at the achievement of temperature measurement with high sensitivity in the sub-wavelength scale, an all-metal meta-surface (amms)-based sensor is numerically demonstrated. based on the sharp plasmonic resonances and the simultaneous use of perfect absorption response, temperature sensing with an ultra-high enhancement factor of 263 for the spectral figure of merit (fom) factor is obtained in comparison with that of the common plasmonic sensors. moreover, spectral shift-related sensitivity s is up to 0.274 nm/°c. these sensing properties indicate the designed sensor can play a significant role in optoelectronic devices for high-integrated and high signal-to-noise ratio temperature detection.
