“…The atomic force microscopy (AFM) scan result is shown in Figure 4. A prototype LRSP device with a structure similar to a spectral notch filter [21] is made for SPR testing purpose. To best eliminate particle contamination in the device, the following operations are taken place in a class 100 clean room.…”

“…Previous studies have demonstrated the design approach to reduce the FWHM of SPR by replacing continuous metallic thin films with subwavelength metallic grating structures [20]. Various devices, such as EO modulators, spectral notch filters, and refractive index sensors, have been studied theoretically to show the significantly improved device performance [20][21][22].…”

In this paper, long range surface plasmon devices using metallic subwavelength gratings are experimentally demonstrated. Subwavelength gold gratings are fabricated with deep UV interference lithography. Long range surface plasmon device using these subwavelength gold gratings is characterized by measuring the surface plasmon resonance reflectance curve in an attenuated total reflection setup. Surface plasmon resonance curve with approximately ten times narrower angular width than that from long range surface plasmon propagating along metallic thin films has been observed experimentally.

“…The stop band of the reflection-type angle-independent filter can also be adjusted by varying the structure geometry. The angle-independent and ultra-narrow bandwidth features make the designed filter more flexible than either guided-mode resonance (GMR) dielectric filter [13][14][15] or plasmonic filter [16,17].…”

Ultra-narrow linewidth, angle insensitive guide-mode resonance filter (GMRF) has been designed. The aimed performance on the behavior of the filter with respect to the angular divergence of the incident beam was considered. Results show that high reflection (more than 99.9%) can be obtained at the resonance wavelength, the full-width at half maximum (FWHM ) of TE-polarized light is only 1.1×10 -3 μm, and its sideband reflectance from 0.565 to 0.625 μm is less than 1%. In contrast to the ordinary GMRF, where the location of the resonances is incident angle dependent, it is demonstrated that the maximum peaks of the reflected spectrum gradually decreases with respect to the incident angle, but the reflectance peak position does not change.

“…Under certain conditions, the free electrons of metal surfaces produce collective coherent oscillation, which is stimulated by light; the electromagnetic wave at the metal/air interface is called SP [ 18 , 19 ]. The internal quantum efficiency and external quantum efficiency of LEDs can be improved by using SPs.…”

To improve the light extraction efficiency of light-emitting diodes (LEDs), grating patterns were etched on GaN and silver film surfaces. The grating-patterned surface etching enabled the establishment of an LED model with a double-grating displacement structure that is based on the surface plasmon resonance principle. A numerical simulation was conducted using the finite difference time domain method. The influence of different grating periods for GaN surface and silver film thickness on light extraction efficiency was analyzed. The light extraction efficiency of LEDs was highest when the grating period satisfied grating coupling conditions. The wavelength of the highest value was also close to the light wavelength of the medium. The plasmon resonance frequencies on both sides of the silver film were affected by silver film thickness. With increasing film thickness, plasmon resonance frequency tended toward the same value and light extraction efficiency reached its maximum. When the grating period for the GaN surface was 365 nm and the silver film thickness was 390 nm, light extraction efficiency reached a maximum of 55%.
