Crack resistant sol-gel wafer coatings for integrated optics

   
   

A method of preparing a multi-layer, crack resistant sol-gel glass derived coating on a substrate by removing the outer periphery of each layer before curing the layer and depositing any succeeding layer.

Un metodo di preparazione dell'a piĆ¹ strati, vetro resistente del solenoide-gel della crepa ha derivato ricoprire su un substrato rimuovendo la periferia esterna di ogni strato prima del trattamento dello strato e del depositare qualsiasi strato successivo.
