<p><P>PROBLEM TO BE SOLVED: To provide an optical switch which operates at a shorter switching rate, and to provide its manufacturing method. <P>SOLUTION: In the optical switch to switch transmission routes of optical signals by changing the refractive index by injecting a carrier, the recombination level in the optical waveguide layer where optical waveguides to propagate light signals are formed is increased. <P>COPYRIGHT: (C)2004,JPO</p> |
