Abstract
An optical fiber is bent to form a discontinuous curve through which light can be injected into the fiber or extracted from the fiber. The bend can be formed by securing a portion of the optical fiber in a fixture and laterally displacing a portion of the fiber outside the fixture using a depressor. The depressor can be an integral part of the securing fixture or a separate device. The securing fixture can be adjustable so that the degree and location of the bend can be varied. Injected light can be sourced from a second optical fiber, and extracted light can be supplied to a second optical fiber which can have a lens at its free end.
