摘要:
A waveguide element is capable of realizing acute waveguide discontinuity, such as a right angle bending, (L-shaped bending) or branching (T-shaped branching). Two single mode waveguides having the identical cross-sectional structure form a waveguide discontinuity where center axes thereof extending in the longitudinal direction intersect with each other at an angle &thgr; (0
