摘要
The device has at least one first input and output, a first phase shift stage (10) with a first phase shift element, a first delay stage (12) connected to the first phase shift stage and containing a second phase shift element, a second shift stage (14) connected to the delay stage and with a third phase shift element, forming a Mach-Zehnder structure. The phase shift elements (41,44,16) are controlled to produce a defined delay. Independent claims are also included for the following: (1) a method of achieving a desired signal delay with an inventive device; (2) an optical receiver with an inventive device; (3) a polarization dispersion compensator; (4) an optical multiplexer; and (5) an optical router.
