Volume 74, Issue 7. July 1991 ... bop sis technicianThe thermo-optic coefficient of a material is the change in refractive index with the response to temperature. This value itself also depends on the present temperature of the material and so has second-order behaviours. At low temperatures (0-400°C), the relationship is linear but at higher ones it exhibits a second-order polynomial behaviour. haunted banks
