Sub-terahertz (sub-THz) waves, operating in the 0.1-1 THz band, offer significant potential for next-generation 6G systems. These systems stand to benefit from photonic technologies that enable terabits-per-second communication with low latency and h

In this article, we propose, design, and numerically assess a novel parametric refractive index profile for optical fiber, which we refer to as reciprocal-inverse graded index fiber (R-IGIF). The R-IGIF features a shape parameter $\alpha$ that contro

Among all optical sensing techniques, the distributed Sagnac loop (SI) sensor has the advantage of being simple to implement with low cost. Most of the proposed techniques for using SI exploit the frequency null method for event localization. However
