Title: Optical device
Inventor: MURATA HISASHI
IPC: G11B7/135
Filed: 2001-04-24
Abstract: PROBLEM TO BE SOLVED: To provide an optical device which can deal with laser beams having a different wavelength with the small number of components by realizing the sharing of the components. SOLUTION: The cost of an optical member 2 is reduced by forming a relief type diffraction grating 2a on one surface of the optical member 2. The primary diffracted light of an S-polarized light wave can be emitted in the direction of a Disk D, by introducing a laser beam so that the angle of incidence θ1 of the laser beam on the diffraction grating 2a satisfies the Bragg condition. A return light beam from the Disk D is converted into a P-polarized light wave by a quarter-wave plate 7, and diffraction transmission (refraction) of zero-order is produced by the diffraction grating 2a. Thereby, emitted light is turned in the direction of a light receiving element 4. The use efficiency of the laser beam can be improved because diffraction efficiency in the primary diffraction transmission and the diffraction transmission of zero-order is high.
