Abstract
Cladding removed from a portion of the optical fiber defines a window exposing the fiber core. A grating having a substantially periodic structure defining a wavelength is moveably positioned in the window, where it can interact with the evanescent field present in the window when optical power is propagating through the fiber. An adjustable positioning fixture holds the grating proximate to the window and operates to change the relative spacing of the fiber core and grating, between: a first position in which the grating is held proximate to the fiber core and substantially interacts with the evanescent field, and a second position in which the grating is held apart from the fiber core and does not substantially interact with the evanescent field.
