Surface Plasmon Resonance Based Fiber Optic Sensors
In recent years, the phenomenon of surface plasmon resonance (SPR) has fascinated a large number of researchers across the world due to its usefulness in various optical devices. Surface plasmons are the electromagnetic excitations generated due to charge density fluctuations at the interface between a metal and a dielectric. These are transverse magnetically (TM) polarized waves that travel along the interface. The field associated with these waves decays exponentially in both the media (metal and dielectric). Because of TM polarized wave, surface plasmons can be excited by a TM or p-polarized light. The resonance between the two occurs when their wave vectors are equal resulting in the transfer of energy to from incident light to surface plasmon wave. The wave vector of surface plasmon wave depends on the dielectric constant of the medium in contact of the metal.
