论文摘要
通过在非线性相互作用介质中混合泵波来对输入波的光学扩增为各种应用提供了很高的增长。在现实生活研究中，允许输入波的光学扩增的相互作用介质具有许多共振频率。但是，调整泵频率以产生输入波的光学放大的计算费用随着相互作用介质内的共振频率数量而增加。在这里，我们提出了一种基于Fletcher-Reeves的算法，用于具有多个共振频率的微谐振器中的参数扩增。使用我们的新数学公式，我们在640 THz处的输入波获得了4.7x107的增益，在微谐振器中100THz的输入波的增益为1.5x108。此外，我们的算法的性能通过众所周知的数学表达来验证，我们在光学扩增的计算中获得了超过99％的精度。据我们所知，这是第一项研究，其中弗莱彻 - 里弗斯算法用于参数放大。我们的方法可以伴随着设计光学参数放大器，以应用高速光学通信，光子电路和超快激光器。
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 4.7x107 for the input wave at 640 THz and a gain of 1.5x108 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.
