Abstract

Spatial holographic multiplexing with a photothermoplastic device is an attractive solution for interconnection of high bit rate channels in a telecommunication network. Because the wavelength of the recording beams is largely different from the wavelength of the IR reading beams, a symetrical two-stages optical configuration is required to keep optical aberrations as low as possible. Such a configuration is described here, which enables interconnection of input single-mode fibers to output single-mode fibers. Concerning the material properties, another problem has been solved: by using a self-stabilized thermoplastic molecule, large cyclability (80,000 cycles) is demonstrated with a high diffraction efficiency of the holographic recorded gratings.
