TL;DR: In this article, the authors use the splice loss measurement technique in absence and presence of angular misalignment and report a simple and accurate method to predict the unknown aspect ratio of a supplied circular core trapezoidal index single mode fiber.

TL;DR: Based on the splice loss analysis between two perfectly aligned single mode step and trapezoidal index fibers, a simple empirical relation of power transmission coefficient in terms of normalised frequency and aspect ratio was proposed in this article.

TL;DR: In this paper , the effect of aspect ratio on splice loss between a pair of identical single mode trapezoidal index fibers in the presence of longitudinal and transverse misalignments is investigated.
Abstract: In this paper, an in-depth investigation is carried out on the effect of aspect ratio on splice loss between a pair of identical single mode trapezoidal index fibers in the presence of longitudinal and transverse misalignments. Splice loss is, interestingly, observed to get reduced, with the increase of aspect ratio and becomes minimum for unit aspect ratio for step profiles. Also, it is nearing minimum for near-step profiles. So, if there exists a little imperfection, say about ten percent, from step index profile, there will be no significant increase in the loss than that in step profile. This extended loss-tolerant feature in the step and near-step region revalidates the choice of the available step profile, technically used in communication. Thus, even for a digression in fabrication, system users should feel confident to use it. The physical significance of the results is justified from basic diffraction ideas. Finally, the entire study leads to a novel proposal of a longitudinal displacement sensor through simple and straight-forward empirical formulation to estimate the longitudinal misalignment from the knowledge of the splice loss of widely available step index fiber simply with air in the gap.

TL;DR: In this paper, a simple and straight-forward method is presented for prediction of unknown aspect ratio of a given single mode trapezoidal index fiber, using splice loss technique in presence of lateral offset at the splice between them.

TL;DR: The results show that the angle error of 90° splice has a significant influence on the system output, and the tolerance of angle error varies with different test voltages, and this research provides a reference for the development of fiber voltage sensor based on the converse piezoelectric effect.
Abstract: In fiber voltage sensor, imperfect fiber splicing angle and length difference between the sensing fiber and the compensating fiber usually influence the system output performance. This article esta...
