Abstract
A method of manipulating an optical signal includes a) splitting the optical signal into a first signal and a second signal, b) using the second signal as a signal undelayed with respect to the optical signal, c) delaying the first signal with respect to the second signal, d) splitting the first signal into a first and a second part, e) using the second part of the first signal as a delayed signal, and f) repeating steps a)-d) with the first part of the first signal.

A method of manipulating an optical signal, comprising the steps of:
- a) splitting the optical signal into a first signal and a second signal,
- b) using the second signal as a signal undelayed with respect to the optical signal,
- c) delaying the first signal with respect to the second signal,
- d) splitting the first signal into a first and a second part,
- e) using the second part of the first signal as a delayed signal, and
- f) repeating steps a)-d) with the first part of the first signal.
3 more elements
An apparatus for manipulating an optical signal, comprising:
- a first splitting device for splitting the optical signal into a first signal and a second signal,
- a delaying device for delaying the first signal with respect to the second signal so that the second signal can be used as a signal undelayed with respect to the optical signal,
- a second splitting device for splitting the first signal into a first and a second part, so that the second part of the first signal can be used as a delayed signal, and
- a repeating device for providing the first part of the first signal to the first splitting device.
