Article: Tunable microring resonator based on dielectric-loaded surface plasmon polariton waveguides.
[show abstract] [hide abstract]
ABSTRACT: Integrated optical ring resonators are essential elemental components for integrated optical circuits. An ultrasmall thermo-optical microring resonator with two bus waveguide-configuration based on surface plasmon polariton waveguide is theoretically analyzed. The thermo-optical coefficient, the temperature-dependent amplitude attenuation coefficient and the temperature distribution properties of the waveguide are investigated numerically by finite element method. The critical resonant conditions of the microring resonator are discussed by considering the propagation losses in the plasmonic ring cavity. The transmission characteristics and the tunability of the ring resonator with different structural parameters are investigated. The results show that the proposed ring resonator with a low driving power and high efficient tunability has potential to develop nano-scope wavelength tunable channel drop filters, low power optical switches, attenuators, and other high compact integrated optical devices.Journal of Nanoscience and Nanotechnology 12/2011; 11(12):10520-4. · 1.56 Impact Factor -
Conference Proceeding: A novel thermal controlled optical attenuator
[show abstract] [hide abstract]
ABSTRACT: A novel thermal controlled optical attenuator based on symmetric dielectric-loaded surface plasmon polariton (SDLSPP) waveguide is proposed and theoretically analyzed in this work. The mode effective indices, propagation lengths, the temperature dependent characteristic are analyzed using a finite-element method (FEM). Such device can be controlled by low driving power and shows excellent tunability. The optical attenuator provides a potential for novel temperature-tunable surface plasmon polariton (SPP) devices.Nanoelectronics Conference (INEC), 2010 3rd International; 02/2010
