Optical fibre lattice signal processors. |
摘要 |
<p>The optical fibre lattice signal processor comprises at least two coupling devices through which two optical fibres pass in a manner permitting optical coupling therebetween. The optical coupling devices are arranged in parallel with respect to each other and each fibre experiences a 180 DEG turn between the couplers. Recursive and non-recursive arrangements are provided for, together with equal and arbitrary delays.</p> |
