Tapered optical fibers using CO2 laser and their sensing performances

In this paper, we proposed a simple tapering process of optical fibers using controlled CO2 laser. This is a response to the call for the rapid development of affordable, efficient, and reliable optical sensors. A laser with power of 36 W was focused on a small section of three optical fibers having...
