Digital optical switch for use in optical delay line, has electrodes partially covering input guide from junction point to another junction point, where electrodes are self aligned with input guide for forming lines

摘要

The switch has output guides connected to an input guide, and electrodes (61, 62) self- aligned at the output guides from a junction point (A) of the output guides to lines (B0B1, B0'B1'). The electrodes partially cover the input guide from a junction point (C) to the junction point (A), where the electrodes are self aligned with the input guide in an enlargement zone (110) for forming lines (CB0, C'B0).
