Abstract :
We present a simple fabrication method for embedding gold nanoparticles (GNPs) in a microfiber with two main advantages. The GNPs are positioned within the microfiber securing maximum enhancement of the electrical field and protection of the GNPs from the surroundings; moreover incoupling losses to the microfiber are reduced significantly by integrating a single mode fiber in the device. The average enhancement factor of the electric field within one unit cell of the microfiber due to the GNPs is estimated to 17.4. This enhancement leads to an enhanced Kerr effect near the plasmon resonance frequency. The fabrication method is demonstrated without GNPs.
