“…In the simulation, by solving the eigenvalue equation of the fiber, the effective refractive indices of the LP01 and LP11 modes are obtained as neff01 and neff11, respectively, and the respective coupling coefficients cv are obtained, as shown in Figure 3, according to the formula (5). Based on the above theoretical analysis, the multi-layer film transmission matrix method is used to numerically simulate and analyze the reflection lines corresponding to different modes of the doubleclad fiber grating.…”

In this paper, the preparation and spectral properties of large mode field double-clad (LMA) fiber two-dimensional fiber gratings are studied. Firstly, a new compact grating analysis model for writing fiber gratings with different periods in different regions of the fiber core is theoretically proposed, and the spectral characteristics of the gratings written in different regions of the fiber core are studied based on the transfer matrix method. A three-wavelength two-dimensional fiber grating with a designed wavelength interval of 1.57 nm was successfully fabricated using a 248 nm excimer laser in a large mode field double-clad fiber laser. The research results show that the spectral characteristics of the two-dimensional fiber grating can be changed flexibly by changing the masking parameters, and the structure is compact. The experimentally obtained two-dimensional fiber grating spectrum is consistent with the theoretical analysis. The research results provide a theoretical reference for the design, fabrication and application of two-dimensional fiber gratings.

With the increasing use of internet and mobile phones, the capacity of the backbone optical communication link has been continually growing across the world and especially in India. The total optical fiber cable deployed for the BharatNet initiative of Government of India is expected to increase from 3.4 million km to 5 million km in 2024-25 just for providing lastmile connectivity. Considering this deep proliferation, this article attempts to capture the diverse research carried out in India in the domain of optical communication.

“…Fiber optic communication has become one of the main pillars of power communication with its high capacity, anti-interference, low cost, long transmission distance, and fast speed, and it plays a pivotal role in modern power communication networks [1]- [2]. As the main transmission medium of power communication highway, once the fiber optic failure occurs, the interruption for a long time will seriously affect the safety production of the power system [3]- [4]. Therefore, the reliability of fiber optic transmission network operation is an important guarantee for the power system's effective operation and secure production [5]- [6].…”

With the arrival of the big data era and the development of new network technology, how to use big data technology to diagnose and locate fiber optic cable faults in communication networks has become a hot topic of current concern. Firstly, a combined generative adversarial network and convolutional neural network algorithm is proposed based on a deep learning algorithm, then an improved fault diagnosis model combining generative adversarial network and convolutional neural network algorithm is built, and finally, the combined generative adversarial network and convolutional neural network model is used to verify and analyze the fiber optic cable fault diagnosis. The results show that the accuracy of the DCGAN-CNN algorithm for fiber optic cable fault diagnosis is 98.5%, and the research results verify the effectiveness of the combined generative adversarial network and convolutional neural network model for fiber optic cable fault diagnosis. This study can accurately and comprehensively solve the problem of fiber optic cable faults in communication networks and thus play a guiding reference value for developing fault diagnosis in Chinese communication networks.
