Recent advances in artificial intelligence (AI) have inspired researchers to explore machine learning (ML)based optimization and reverse design techniques for photonic crystal fibers (PCFs). These studies often seek to improve model generalization, particularly for data that the model has not previously encountered. Traditional centralized training methods are challenging for devices with limited resources, as they rely on aggregating expansive datasets, which is hindered by constraints in storage capacity and communication efficiency. This paper introduces an innovative distributed framework for optimizing PCF parameters, utilizing decentralized training to amalgamate knowledge across various institutions while maintaining data privacy. Each institution develops a lightweight neural network using a small subset of local data, contributing to the construction of a collective and robust global model. This approach is advantageous for both internal and external applications in PCF engineering. Rigorous empirical experiments conducted with real-world PCF optimization data substantiate the efficacy and benefits of the proposed framework. This framework shows promise in achieving an equilibrium between data protection and resource efficiency, offering a novel platform for the reverse design of microstructured optical fibers.
We present the experimental realization of a compact and fully automized volume holographic memory based on phase-coded multiplexing that is capable of both, high-resolution analog image and digital datastorage, havi...

Silver oxide thin-films with various silver oxides concentration and silver particles amounts are prepared via magnetron sputtering techniques with oxygen reactive gas by varying deposition parameters. The presence of silver particles in the inorganic silver oxide compound was detected by x-ray diffraction. Heat measurements of the powdered silver oxide film via thermogravimetry analyzer (TGA) show that the powdered silver oxide decomposes and releases oxygen at a temperature of about 355 degrees C. The oxygen concentration can be estimated by TGA weight loss. The optical reflectance and extinction coefficient of the silver oxide film confirm the dual function of the silver particles present in the film. The silver particles served both as the laser beam light absrober and reflectance centers for laser beam. With the presence of the silver particles in the silver oxide film, the reflective layer used in the prior art can be dispensed with. A single layer disk-silver dispersed silver oxide film, which served both as the recording layer and the reflective layer, deposited on the digital versatile disk-recordable (DVD-R) polycarbonate substrate is prepared. Since the plastic substrate is softened at a temperature of about 140 degrees C, the silver oxide recording layer decomposes and releases oxygen when the recording medium is irradiated with a laser beam so as to permit formation of recesses in the plastic substrate and so as to permit a sharp change in reflectivity at positions where the recessions are formed. The characteristics of this single layer DVD-R disk are demonstrated.
