Abstract
A tightly bending loss technique is developed for application in biomedical WDM fiber sensors. In this paper, we present the measurement and comparison of bending sensor in 1.3 (mu) m and 1.55 (mu) m wavelength region, respectively. A two-wavelength measurement setup is built for bending loss testing. Various wrapping method and turns are invested for studying the bending loss for broadband biomedical sensing system. We found that as the bending loss increases, the oblique angle of wrapping becomes large. These research results is helpful for multi-channel multi- array fiber optic biomedical sensor systems.
