Coherent equalization of optical signals |
| abstract |
Coherent optical equalization is applied in the optical domain to an input optical signal that includes a wanted optical signal and an unwanted optical signal temporally delayed relative to the wanted optical signal. A first optical signal that includes at least the wanted optical signal is split into first beams that include a first beam subject to delay. The first beam subject to delay is delayed to provide a delayed first beam. Beams that include the delayed first beam are coherently summed to produce a second optical signal in which the unwanted optical signal has a reduced intensity compared with in the input optical signal. In the coherent summing, the instance of the wanted optical signal in the delayed first beam cancels the unwanted optical signal in another of the beams that are coherently summed. |
