Thermal properties of highly birefringent optical fibres and preforms
Ourmazd, A., Varnham, M.P., Birch, R.D. and Payne, D.N. (1983) Thermal properties of highly birefringent optical fibres and preforms. Applied Optics, 22, (15), 2374-2379. (doi:10.1364/AO.22.002374).
Temperature cycling of highly birefringent optical fibers and preforms has been used to investigate the thermal properties of bow-tie and elliptically clad structures. The thermal hysteresis of the birefringence is shown to be a direct consequence of the thermal history of the fiber or preform and has been related to volume changes in the stress-producing borosilicate sections. Annealing increases the axial stress as well as the stress anisotropy and hence the birefringence. Increases of up to a factor of 2 in the birefringence on suitable thermal treatment indicate a new method for further improvement of high birefringence fibers. The implications of the results in the design, fabrication, and use of such fibers are discussed.
