Title: Photonic crystal directional coupler
Inventor: YAMAMOTO MUNETSUGU
IPC: G02B6/12
Filed: 2005-11-14
Abstract: <P>PROBLEM TO BE SOLVED: To make the coupling length and the high extinction ratio coexist by breaking through the relation of trade off between the coupling ratio and the extinction ratio.  <P>SOLUTION: The photonic crystal directional coupler is composed of three directional coupler waveguides of A, B, and C, and each of them is provided with a common reflective symmetry plane. The A and C are the directional couplers of small energy distribution difference between odd/even modes, and the B is the directional coupler of large energy distribution difference between the odd/even modes. Because, the A, B, and C are provided with a common reflective symmetry plane, in the connection between A and B and the connection between B and C, the excitation is performed at only from the odd mode to the odd mode, and from the even mode to the even mode, and neither performed from the even mode to the odd mode nor from the odd mode to the even mode. The serially connected three directional coupler wave guides are constituted of photonic crystal. Boundaries between the central directional coupler wave guide and its both sided two directional coupler wave guides are directly connected or provided with connection regions of prescribed lengths while keeping the reflection symmetry.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
