Abstract:
A periodic grating structure is placed on a facing surface formed on an optical fiber so that the grating structure is within a portion of the evanescent field of an optical signal propagating through the optical fiber. The spatial periodicity of the grating structure is selected to be equal to one-half the propagation wavelength of the optical signal. The grating structure causes the optical signal to be reflected at an angle of 180 degress and thus to propagate in a reverse direction from its original direction of propagation.
