PROCEDE ET DISPOSITIF DE FABRICATION D'UN MONOCRISTAL, EXEMPT DE TOUTE CONTRAINTE, D'UN COMPOSE FERROELECTRIQUE A STRUCTURE CRISTALLINE |
摘要 |
The process involves producing a monocrystal from the ferroelectric compound, annealing the monocrystal and cooling the latter in a zero longitudinal temperature gradient. The apparatus comprises means for producing the monocrystal and heating means for annealing the monocrystal in a zero temperature gradient, as well as for cooling the monocrystal in a zero longitudinal temperature gradient after annealing. The strain-free monocrystals may be used in the production of surface wave filters, modulators and optical amplifiers. |
