Nanoscale plasmonic filter based on coupled metal-insulator-metal waveguides using nonlinear nanoslot resonator Hamed Arianfard Rahim Ghayour Downloaded From: http://nanophotonics.spiedigitallibrary.org/ on 05/14/2015 Terms of Use: http://spiedl.org/termsNanoscale plasmonic filter based on coupled metal-insulator-metal waveguides using nonlinear nanoslot resonator Abstract. A nanoscale optical filter based on metal-insulator-metal waveguides and a Kerr-type nonlinear nanoslot resonator is introduced and numerically investigated by finite-difference time-domain simulations. It is demonstrated that the resonant wavelengths of the nanoslot resonator experience a red shift due to the intensity dependence of the Kerr nonlinear effect. The simulation results reveal that the resonant modes of the proposed filter can be tuned by properly adjusting the input signal intensity without changing the dimensions of the filter structure. The findings of this study are useful for highly integrated optical circuits, for which we have limitations on the dimensions of the filter structure. In addition, the results are suitable for design of integrated optical waveguides and resonators based on the plasmonic effect. A significant advantage of the proposed tunable filter is its ease of fabrication.Arianfard and Ghayour: Nanoscale plasmonic filter based on coupled metal-insulator-metal waveguides.

Plasmonic sensors are well known for their miniaturized size and high sensitivity. Herein, a numerical analysis of a metal‐insulator‐metal (MIM) waveguide (WG) for refractive index (RI) sensing applications is proposed. The sensing device is composed of a MIM bus WG with a semicircular formation side coupled to a semicircular cavity. This configuration provides a transmission dip with a high extinction ratio as compared to the standard MIM WG side‐coupled to a semicircular cavity. Moreover, the mode converters are also embedded in the sensing system solving the obstacle of light coupling to the MIM plasmonic WG. The sensitivity of the proposed device is ≈941.33 nm RIU−1, making it a promising candidate to be employed in point‐of‐care (POC) testing. This typically involves the use of portable or handheld diagnostic devices that can quickly analyze samples of blood, urine, or other bodily fluids to diagnose diseases or conditions such as infections, diabetes, or heart disease.

“…Compared to conventional dielectric optical waveguides, SPP waveguides have unique properties, including subwavelength confinement and field enhancement [2], which may have great potential in applications such as nanophotonics [3], [4], spectroscopy [5], [6], and sensing [7], [8]. Unfortunately, the propagation distances of SPP mode are usually limited in tens or hundreds of micrometers long because of extremely high waveguide loss caused by the intrinsic absorption of the metal.…”

A rate-equation theory model with the amplified spontaneous emission (ASE) effect considered for the surface plasmon polariton (SPP) waveguide amplifier is presented for analyzing the SPP amplifications with both side and SPP pumping techniques. By partitioning the cross section of the waveguide to suitable small units and introducing the overlapping integrated factor in each unit, the 3-D coupled equations of the model can be simplified to 1-D equations, which could be solved more conveniently. With our model, the gain and noise properties of a dielectric-loaded SPP waveguide amplifier are simulated. The results show that the ASE effect reduces the signal gain and deteriorates the signal-to-noise ratio of the SPP amplifier. For both the pumping schemes, the gains and noises for SPP multimode amplifications depend on the waveguide structure. By optimizing the waveguide structure, the gainequalized amplification for different SPP modes may be achieved.
