IPC: G02B6/126
Filed: 1990-11-07
Abstract: PURPOSE:To dispense with assembly and regulation and to produce a polarizing beam splitter being easily miniaturized on account of two dimensional structure by diffusing titanium on a lithium niobate base to form a titanium diffused layer, and executing proton exchanging treatment on the part of the titanium diffused layer. CONSTITUTION:Titanium is vapor-deposited on the ground face of a Y-cut lithium niobate base by spattering or the like to form a thin titanium film, which is heated at about 1,000 deg.C to diffuse the titanium inside the base for forming a titanium diffused layer. A partial domain on the surface of the titanium diffused layer is masked by acid resistant metal such as tantalum to proton-exchange an unmasked domain using benzoic acid, pyrophosphric acid or the like. On the boundary face between these two domains, a straight polarizing beam on a polarizing face along the fixed direction permeates, and the straight polarizing beam on the polarizing face in a direction different from the fixed one reflects. Thus a light wave directing path and a polarizing beam splitter can be unitedly formed on the same base.
