Paper Abstract

One of the techniques for fiber-to-fiber connection is based on a basic interferometric method to obtain a holographic grating acting as a holocoupler. Holographic couplers can be used as memory systems storing information to achieve single or multiple fiber connections using a multiplexed hologram. This device works with high efficiency in short intervals of space and time. Applications can be extended, as well, to codify the stored information in a reflection configuration as a switcher system with a laser diode. The flexibility of this technique allows coupling of alternative focusing elements such as two GRIN lenses and other configurations. In order to develop this application in optoelectronic devices, the recording process must by carefully analyzed. The recording of the holograms has been already resolved for planar and spherical waves. Nevertheless, recordings with Gaussian waves require some conditions to be accounted for due to the width waist and divergence of the output beam of the laser source.
