A super frequency-shifter: enhancing the capabilities of acousto-optic modulators
[ANGLÈS] We put forward a new scheme to enhance the capabilities of currently available acousto-optic frequency shifters (AOFS) by making use of the idea of weak value amplification. The key result of our approach is that the spectrum of a pulse of light can be shifted in frequency by an amount cons...

| Sumario: | [ANGLÈS] We put forward a new scheme to enhance the capabilities of currently available acousto-optic frequency shifters (AOFS) by making use of the idea of weak value amplification. The key result of our approach is that the spectrum of a pulse of light can be shifted in frequency by an amount considerable larger that the original AOFS can in principle allow. For instance, a pulse with central wavelength at 1550 nm (193.5 THz), and pulse duration of 0.5 ps, can be shifted in frequency by more than 50 GHz (0.4 nm), by making use of just a 100 MHz AOFS in a single pass configuration. More remarkably, by using a similar configuration, and replacing the AOFS by a delay line, a frequency shift can also be obtained, even without making use of any frequency shifter. |
