Porous Materials and Optical Glass

YTCA has extensive experience and strong intellectual property positions in the development of porous materials using sol-gel and other liquid-based techniques. Porous ceramic sensor substrates developed at YTCA are currently being commercially produced. In addition, materials with engineered porosity have been developed for technologically challenging applications in the semiconductor industry. YTCA has also developed proprietary processes for drying large sol-gel monoliths without cracking, thereby solving a problem that has plagued researchers in the field for decades.

Engineered porous materials prepared using these methods can be sintered into ultra-pure glasses for use in the fiber optic and semiconductor industries, for example. Cylindrical porous bodies have been doped and sintered to prepare optical fiber performs with tightly controlled refractive index gradients. High quality UV optical components meeting the stringent specifications from International SEMATECH have also been prepared using this method. Techniques developed at YTCA can be applied to produce technical glasses for a wide range of applications.
