る。従来この種のガラスはガラス原料と半導体を高温で
溶融・混合させ、その後急冷することにより得られてい
た。Glass in which semiconductor fine particles are dispersed is used in optical elements such as wavelength filters, and since it has even greater nonlinear optical properties, it is expected to be used in optical switches and the like. Conventionally, this type of glass has been obtained by melting and mixing glass raw materials and semiconductors at high temperatures and then rapidly cooling them.
半導体微粒子を分散させたガラスの非線形特性を大きく

かつ均一にし、また、ガラス中に半導体を均一に分散さ
せつつ半導体の密度を高くすることが望ましい。In order to increase the nonlinear characteristics of glass in which semiconductor fine particles are dispersed, the semiconductor particle size must be reduced to about 10λ,
It is desirable to increase the density of the semiconductor while uniformly dispersing the semiconductor in the glass.

めには必要であるが、従来製法では、溶融・混合する段
階で容器等から不純物が混入し易かった。With conventional manufacturing methods, it is difficult to uniformly disperse small semiconductor particles with a uniform particle size in glass at a high density, and the particle size is only about 100 particles and the density (volume ratio) is less than a few percent. I couldn't get it. Furthermore, it is necessary to have a small amount of impurities other than glass raw materials and semiconductors in order to increase nonlinear characteristics, but in conventional manufacturing methods, impurities easily get mixed in from containers etc. during the melting and mixing stage.

By doing so, it is possible to easily disperse the semiconductor uniformly within the glass. Furthermore, since the semiconductor particles are generated within the pores of the porous glass, the semiconductor particle size can be easily controlled by the pore size of the porous glass. Further, since products other than semiconductors, such as NaCl, are vaporized during the sintering step, no special removal step is necessary.

Since this method can be carried out under the same conditions as the method for producing high-purity glass for optical fibers, it is possible to easily produce high-purity semiconductor fine particle-dispersed quartz glass.
