| 摘要 |
This invention describes a system and a method for realizing an adjustable optical delay system that is based on using an optical switch. The outputs of the optical switch are connected to its inputs with optical fiber with predefined lengths: d1, d2, . . . , dj, . . . , dN, then changing the optical switch configuration forms an optical delay line with an optical fiber length that is the concatenation of any subset of the optical fibers with predefined lengths.
