Abstract:

The research program to develop low loss glass fiber optic waveguides involves a novel technique called Molecular Stuffing, which may be used to produce any desired index profile in a porous glass preform such as the phasil rods developed in our laboratory. The nature of this process is such that relatively inexpensive raw materials may be used as starting materials. The purification steps which result in an ultrapure glass preform are done in such a manner that costly clean room procedures are avoided and glass production and processing can be done at relatively low temperatures. This process thus offers an alternative to ultrapure glass melting or chemical vapor deposition which require costly processing procedures andor raw materials. A further characteristic of Molecular Stuffing is that it is possible to produce high numerical aperture step or parabolic index profiles. During this year considerable progress has been made in defining the criteria for obtaining dopants to be used in the Molecular Stuffing process. In this respect the results of the work presented in terms of a description of the Molecular Stuffing procedure as it exists at this time.
