“…As a result, in many applications, the limited gain-bandwidth product constrains the performance and capabilities of the overall optical system as lasers are usually the most fundamental component in an integrated optical system. This limitation of stimulated emission based amplifiers can be avoided by using optical parametric amplifiers (OPAs) which can simultaneously provide a very high optical gain, and a large user-controlled bandwidth, thereby allowing for a huge gain-bandwidth product [8][9][10][11]. For this reason, at first sight OPAs may seem to be the ultimate solution to enhance the amplification capabilities of integrated optical devices.…”

Nanoscale conductive materials are often used for inducing localized free electron oscillations known as plasmons. This is due to their high electronic excitability under optical irradiation owing to their super-small volume. Recently, plasmons have been of interest for enhancing the gain-bandwidth product of optical amplifiers. There are currently two well-established mechanisms for light amplification. The first one is via stimulated emission of radiation (lasers) using a given energy source and often an optical feedback mechanism. The second one is based on the nonlinear coupling of a low-intensity input wave and a high-intensity pump wave for energy exchange (parametric amplifiers). Both techniques have shortcomings. Lasers have a small operation bandwidth and offer a limited gain, but require moderate energy pumping to operate. Whereas optical parametric amplifiers (OPAs) offer a high operation bandwidth along with a much higher optical gain, with the drawback of requiring intense pumping to be functional. The aim of this paper is to introduce a technique that combines the advantages and eliminates the drawbacks of both techniques in the nanoscale to allow for a better amplification performance in integrated optical devices. This is achieved by inducing a plasmonic chirp in conductive nanomaterials a.k.a nano-antennas, which enables the confinement of an enormous electric energy density that can be coupled to an input beam for amplification. Using the Finite Difference Time Domain (FDTD) numerical-method with the material parameters of well-known semiconductors, intramaterial condensation of electric energy density is observed in semiconductor nano-antennas for certain plasmonic chirp-frequencies which enables broadband high-gain optical amplification based on free-electron oscillations that is promising for small-scale optical devices requiring a high gain-bandwidth product. The results are in good agreement with semiempirical data.

“…Different designs and scenarios have been proposed to come up with the ideal optical amplifier configuration, especially for the case of OPAs [7][8][9][10][11]. A prominent technique is the creation of artificial materials with extraordinary electrical non-linearity to provide OPA at a lower pump wave intensity.…”

“…Novel ultra-wideband optical antennas, super-efficient harmonic generators 15 , and small-scale optical ablation devices need the optical gain via the non-linear wave mixing process in the micro and nanoscale which is a crucial scientific problem. For achieving significant optical gain in the millimeter or lower scale, specially designed materials showing nonlinear optical properties are required [16][17][18] . Therefore, parametric amplifiers are currently not feasible to be employed in the micro and nanometer scale for high-gain optical amplification with ordinary materials.…”

Optical amplification of the input wave by mixing the pump wave within a nonlinear interaction medium offers high gain for a variety of applications. In real life studies, the interaction mediums which allow the optical amplification of the input wave have many resonance frequencies. However, the computational expense for tuning the pump frequency to yield the optical amplification of the input wave increases with the number of resonance frequencies within the interaction mediums. Here, we present a Fletcher-Reeves based algorithm for parametric amplification in micro-resonators having multiple resonance frequencies. Using our novel mathematical formulations, we obtained a gain of 4.7x10 7 for the input wave at 640 THz and a gain of 1.5x10 8 for the input wave at 100 THz within the micro-resonators. Moreover, the performance of our algorithm is verified by the well know mathematical expression, and we achieved more than 99% accuracy in computation of optical amplification. To our knowledge, this is the first study where Fletcher-Reeves algorithm is used for the parametric amplification. Our methodology can be accompanied to design optical parametric amplifiers for applications of high-speed optical communications, photonic circuits, and ultrafast lasers.
