Filed: 2007-04-02
Abstract: <P>PROBLEM TO BE SOLVED: To solve the following problem: when optical disks of a DVD and a CD are played back in a single device, a light source emitting two wavelengths of light for the DVD and light for the CD is used, two luminous fluxes are used in a common optical path and 3 beams are used for each luminous flux utilizing diffraction light for track adjustment, however, when light having different wavelengths is passed through the same diffraction grating and desired diffraction is generated in one wavelength, favorable diffraction is not always generated in the other wavelength.  <P>SOLUTION: A diffraction element has structure where a sub wavelength structure 13 having a pitch shorter than a wavelength is superimposed on a diffraction grating having a pitch wider than the wavelength, thereby structural birefringence is generated. By utilizing the structural birefringence, diffraction can be generated in one wavelength and diffraction can not be generated in the other wavelength by providing diffraction elements having corresponding wavelengths different from each other on both surfaces of one diffraction member and making respective polarization directions of light orthogonally cross.  <P>COPYRIGHT: (C)2009,JPO&INPIT
