Title: Polarizing beam splitter and magneto-optical pickup device using the same
Inventor: TAKEZOE HIDEO
IPC: G11B11/105
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and to stabilize the performance to the change in temp. and the change in wavelength. SOLUTION: An oriented film 30b consisting of polyethylene terephthalate, etc., is laminated on an optical isotropic substrate 30a and a polarizing film 30c consisting of a double refractive material such as polydiacetylene oriented by this oriented film 30b, is laminated on the oriented film 30. While the S polarized light component to be transmitted is absorbed by this polarizing film 30c, the reflection of a P-polarized light component is made zero by making incident light incident on the splitter at a Brewster angle with the polarizing film from, for example, a polarizing film surface side, thereby, the P polarized light component and the S polarized light component are completely separated and a function as the polarization beam splitter is exhibited.  The structure is thus extremely simplified and the change in the characteristics by the change in the temp. is minimized by using the double refractive material, such as, polydiacetylene. In addition, there is no need for precisely controlling the raggedness, etc., which affect diffraction efficiency, unlike the diffraction grating type of the conventional technique and the polarization beam splitter is so constituted as not to be affected by a wavelength fluctuation.
