Condensation products of silicic acid derivatives and optical waveguide devices using the same |
abstract |
The present invention relates to condensation products of silicic acid derivatives usable especially in optical waveguides and particularly to a condensation product obtained by condensing a silane diol compound (A) of the general formula (1): R 1 2 Si(OR 2 ) 2 (1) wherein R 1 represents a group having at least one aromatic group and having 6 to 20 carbon atoms, and R 2 represents hydrogen (H which may also be a heavy hydrogen D), with a modified silane compound (B) of the general formula (2): R 3 Si(OR 4 ) 3 (2) wherein R 3 represents an organic group having at least one C═C double bond; and R 4 represents a group of C n H 2n+1 (n=a number of 1 or 2), in the molar ratio 1.1 to 1.4:1 [(A):(B)], and to a process for producing the same condensation product, as well as to an optical waveguide device fabricated using the same condensation product. |
