“…The emergence of Extraordinary Optical Transmission (EOT) [9] due to coupling of surface plasmons in a surface lattice has been a breakthrough. It has been widely used and its applications include drug delivery [125], imaging [126,127], color filtering [128,129], high resolution display [130] and high sensitive sensing [131,132]. Since the research in the field of plasmonics is expedited with the discovery of new materials and design fabrication techniques [72,92,133], this review focuses on and evaluates those developments.…”

Color plays an important role in human life: without it life would be dull and monochromatic. Printing color with distinct characteristics, like hue, brightness and saturation, and high resolution, are the main characteristic of image sensing devices. A flexible design of color filter is also desired for angle insensitivity and independence of direction of polarization of incident light. Furthermore, it is important that the designed filter be compatible with the image sensing devices in terms of technology and size. Therefore, color filter requires special care in its design, operation and integration. In this paper, we present a comprehensive review of nanostructured color filter designs described to date and evaluate them in terms of their performance.

“…Plasmonic nanoresonators were also used to develop nanolasers that can deliver energy to the nanoscale on a femtosecond timescale. Nanolasers make it possible to achieve extremely high intensities in the electromagnetic near-field, which is important in high-intensity laser physics as well as in intracavity spectroscopy [ 8 , 9 , 10 , 11 ].…”

“…on the design of the coupled emitter-particle configuration [6,7]. Plasmonic nanoresonators were also used to develop nanolasers that can deliver energy to the nanoscale on fs timescale and make it possible to achieve extremely high intensities in the electromagnetic near-field, which is important in high intensity laser physics as well as in intra-cavity spectroscopy [8,9,10,11]. A seminal paper adopted the macroscopic criteria to nanolasers and uncovered that simultaneously desired is the low threshold of lasing and high threshold of bleaching.…”

Active Individual Nanoresonators Optimized for Lasing and Spasing Operation

Plasmonic nanoresonators consisting of a gold nanorod and a spherical silica core and gold shell, both coated with a gain layer, were optimized to maximize the stimulated emission in the near-field (NF-c-type) and the outcoupling into the far-field (FF-c-type) and to enter into the spasing operation region (NF-c*-type). It was shown that in the case of a moderate dye concentration, the nanorod has more advantages: smaller lasing threshold and larger slope efficiency and larger achieved intensities in the near-field in addition to FF-c-type systems’ smaller gain and outflow threshold, earlier dip-to-peak switching in the spectrum and slightly larger far-field outcoupling efficiency. However, the near-field (far-field) bandwidth is smaller for NF-c-type (FF-c-type) core–shell nanoresonators. In the case of a larger dye concentration (NF-c*-type), although the slope efficiency and near-field intensity remain larger for the nanorod, the core–shell nanoresonator is more advantageous, considering the smaller lasing, outflow, absorption and extinction cross-section thresholds and near-field bandwidth as well as the significantly larger internal and external quantum efficiencies. It was also shown that the strong-coupling of time-competing plasmonic modes accompanies the transition from lasing to spasing occurring, when the extinction cross-section crosses zero. As a result of the most efficient enhancement in the forward direction, the most uniform far-field distribution was achieved.
