Scientists control light echoes for the first time
echoes, because they are not generated by the reflection of waves, but rather in a non-linear optical process. Two short laser pulses are sent to a sample: The first represents the signal and the second the [...] When the lag time of these pulses is doubled, a new light pulse, the photon echo, is emitted by the system exposed to the light.” Using a further control pulse, the researchers were able to control this photon [...] time. Such control is particularly pertinent for nanophotonic circuits in which multiple optical systems need to be precisely synchronised with each other. The phenomenon is set to be further developed …
