Abstract
Optical fibers can be tapered in order to utilize the evanescent field present in the cladding region of the fiber . At the beginning of the taper region most of t he power is present in the core. In the down taper region the light in the core region couples to the cladding region where the evanescent field is present. I n the up taper region, light in the cladding region again couples back into the core region. Our experiment discusses about the process of tapering and the principle of tapered fiber and their optical spectrum .
