Abstract
A surface plasmon polariton (SPP) pixel structure is provided. The SPP pixel structure includes a coupling structure that couples the probing light into the SPP mode by matching the in-plane wave vector by changing the refractive index of the coupling structure using thermo-optic effects to vary the coupling strength of the probing light into the SPP mode. An absorber layer is positioned on the coupling structure for absorbing incident infrared/thermal radiation being detected.
