Title: Manufacturing method of optical waveguide
Inventor: FUKUDA TAKESHI
IPC: G02B6/13
Filed: 2003-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To reduce polarization dependency loss of an optical waveguide by making a mode field shape controllable for an optical waveguide to be obtained and reducing the aspect ratio of the mode field diameter, in forming the optical waveguide inside a transparent material through converged irradiation of a femtosecond laser beam.  <P>SOLUTION: The optical waveguide is formed by inducing a high refractive index area through the converged irradiation of the femtosecond laser beam inside the transparent material such as a fused quartz plate 5. In this case, by varying the pulse width of the femtosecond laser beam, the aspect ratio of the mode field diameter is controlled for the guided beam of the optical waveguide to be formed. Making the pulse width not more than 200 fs for the femtosecond laser beam attains the aspect ratio of 1.4 or below for the mode field diameter. As a result, the polarization dependency loss can be made 0.5 dB or lower which is a practical level as an optical component.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
