The adaptive single-mode fiber (SMF) coupling technique is normally adopted since the coupling efficiency (CE) significantly determines the performance of the free-space optical communication (FSOC) systems. The stochastic parallel gradient descent (

Balloon-Shaped SMF Blood Glucose Concentration and Temperature Sensor Based on Core-Offset Structure
Publikováno v:
Sensors, Vol 24, Iss 19, p 6344 (2024)
A blood glucose concentration and temperature sensor with a balloon-shaped single-mode fiber (SMF) based on a core-offset structure is proposed and experimentally demonstrated. The balloon-shaped SMF is created by offset-fusing a straight-line SMF be
