Title: Optical recording method, optical recording medium and optical recording device
Inventor: KOKUBU YASUO
IPC: G11B7/24035
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To realize high recording density in an optical recording and to realize high density multi-level code recording.  <P>SOLUTION: High recording density can be realized by using the phase difference between orthogonal polarized light rays of an optical wave instead of optical intensity and forming the change of the phase difference between orthogonal polarized light rays of transmission light in a recording medium so that the phase difference between orthogonal polarized light rays of incident light and that of outgoing light are different from each other and high density multi-level code recording can be realized by forming phase differences in multi-levels. In this optical recording method, the change of phase differences between orthogonal polarized light rays of a double refractive film are made partially different and code recording is performed by the change of phase differences between orthogonal polarized light rays. Multi-level cord recording is performed by at least three steps of changes of phase differences between orthogonal polarized light rays of the transmission light. The double refraction film is to be an oriented liquid crystalline polymer film and the change of phase differences between orthogonal polarized light rays of the transmission light is formed by irradiating the oriented liquid crystalline polymer film with UV by changing irradiation time or irradiation intensity.  <P>COPYRIGHT: (C)2003,JPO

Title: Single polarization high-power fiber laser and amplifier
Inventor: FERMANN MARTIN E
IPC: G02B6/44
Filed: 2002-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a fiber which is decreased in the amount of polarization mode coupling and polarization mode dispersion and is increased in polarization maintaining ability and to provide a polarization maintaining high-efficiency fiber amplifier or laser of such a large external diameter that pumping light is guided within an inner clad while a larger outer clad ensures the decrease of the mode coupling in the fiber core. SOLUTION: The high-power polarization maintaining fiber taking the degree of the double refraction of the core, the sectional shape of the clad and the shape for polarization maintaining into consideration is decreased in the stress in the fiber core by increasing the fiber diameter to minimize the polarization mode coupling, by which the polarization mode coupling is minimized and the insensibility of the polarization state with respect to bending and temperature changing of the fiber on the outer side is achieved or the polarization mode coupling is minimized by optimization of the fiber coating in order to minimize the stress at the boundary between the fiber and the coating and eventually the insensibility to the polarization mode coupling is obtained by the value of the double refractivity drastically decreased as compared with the fiber of a small diameter.
