<p><P>PROBLEM TO BE SOLVED: To suppress the degradation of optical characteristics due to thermal stresses and mechanical external forces in an optical component in which a part of a waveguide optical element is fixed to the projected part of a mount. <P>SOLUTION: To a second waveguide optical element 202, first and second optical element support bases 301 and 302 facing each other are fixed separated by a gap from the mount 210. The mount 210 is provided with first and second pressing support bases 311 and 312, and they face each other. A pressing member 313 is arranged on the first and second optical element support bases 301 and 302, and it is fixed separated by a gap between the first and second optical element support bases 301 and 302 by the first and second pressing support bases 311 and 312. The second waveguide optical element 202 and the first and second optical element support bases 301 and 302 are not fixed to surrounding members but are slidable, in a direction which is parallel to the mount 210 (a direction vertical to a paper surface in a Fig.3). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
