OSCILLATOR: applications of Optical SCatterIng and Light LocAlisation in Turbid Or peRiodic media

振荡器的短期目标是提供器件，为光学逻辑（OL），量子处理（QP），安全通信（SEC），先进光纤激光器（AFL）和我们最近开发的超长光纤布拉格光栅（ul - fbg）开辟光子学的新途径。长期目标是完善最先进的Fabulas设施，包括使用fs激光器通过涂层写入光纤滤波器提供超高精度的平面写入（PPW），开发用于机器人和手术导管引导/跟踪的实时显示的新型传感器系统，以及基于互连随机激光器的神经网络，用于研究非线性现象。人工智能（AI）和用于激光冷却和散热的新一代玻璃陶瓷和光纤。这些进步将通过提供出色的设备性能对上述领域产生巨大影响，这是其他方式尚未实现的。成功的成果将提升加拿大的技术竞争优势。制造超高质量的光纤光栅仍然是一个挑战，这将在当前提案的过程中得到解决，要求将相位控制在数百毫米以上的波长的千分之一以下，使用光纤激光器通过涂层进一步复杂化，这严重降低了光纤光栅的质量。为了缓解这些问题，我们需要改进技术，以允许高产量的复制。设备将用于光网络、点对点和卫星通信，其中安全性至关重要，以及实现实时超高速光逻辑操作。预编程随机fbg在弯曲传感和生物医学微创手术导管实时显示方面显示出巨大的前景。这些fbg被组装成三联体用于实时导管跟踪，然而，该应用的数据处理仍然存在挑战。我的实验室最近的发展表明，掺镱纳米晶体玻璃陶瓷样品的产热接近于零。这项正在进行的工作需要关注净化，理论预测这将导致这些易于成型的玻璃冷却，从而开放应用，例如空间传感器和生物光子学。这些材料将制成光纤，通过辐射平衡来减轻高功率光纤激光器的发热。我们的新材料基于弹性体聚二甲基硅氧烷（PDMS）和稀土（RE）掺杂玻璃陶瓷制成了可调谐随机激光器。为什么在某些掺稀土的玻璃中发生淬火需要回答，因为这可能提供广泛的可调性。我们还用锗和其他掺杂剂永久光敏PDMS，并演示了激光简单波导，为集成可调谐光子器件开辟了道路，这些器件与芯片上的实验室兼容，直接用激光写入。

The short-term objectives of OSCILLATOR are to deliver devices to open new avenues in photonics for optical logic (OL), Quantum processing (QP), secure communications (SEC), advanced fibre lasers (AFL) and high-resolution distributed sensing with our recently developed ultra-long fibre Bragg gratings (UL-FBGs). The long-term objectives are the refine the state-of-the-art Fabulas facilities to include ultra-high precision plane-by-plane writing (PPW) using fs lasers to deliver through the coating written optical fibre filters, to develop a new sensor system for real time displays for robotics and surgical catheter guidance/tracking and neural networks based of interconnected random lasers for studying nonlinear phenomenon, artificial intelligence (AI) and a new generation of glass ceramics and optical fibres for laser cooling and heat mitigation. These advances would make a huge impact on the above-mentioned areas by offering outstanding device performance, as yet unattained by other means. Successful outcomes will advance Canada's technological competitive advantage. Fabricating ultra-¬high¬ quality UL¬FBGs has remained a challenge, which will be addressed in the course of the current proposal, requiring the control of phase to less than one thousandth of a wavelength of light over hundreds of mm, further complicated by the use of fs lasers to write through the coating which severely reduces the quality of the FBG. To mitigate these problems, we need to refine the techniques to allow replication with a high yield. Devices will be made for optical networking, point to point and satellite communications where security is of paramount importance, as well as to implement real-time ultrahigh speed optical logic operations. Pre¬programmed random FBGs have shown great promise in bend sensing and real-time display for bio¬medical use with minimally invasive surgical catheters. These FBGs are assembled into triplets for real-time catheter tracking, however, challenges remain in data processing for this application. Recent developments in my lab have shown near zero heat generation in Yb doped nano-crystalline glass ceramic samples. This on¬going work requires a focus on purification, which theory predicts will lead to cooling in these easily mouldable glasses to open applications, e.g., for sensors in space and bio photonics. Optical fibres will be made out of these materials for mitigating heat generation in high power fibre lasers through radiation balancing. Tunable random lasers were made with our new material based on the elastomer, polydimethylsiloxane (PDMS) with rare earth (RE) doped glass ceramics. Why quenching occurs in certain RE: doped glasses needs to be answered as this potentially offers wide tunability. We also permanently photosensitized PDMS with Germania and other dopants, and demonstrated fs laser simple waveguides, and opens avenues to integrate tunable photonic devices compatible with lab-on-a-chip, directly written with lasers.
