[ 產品資訊 ] Acousto-optic applications
AO devices as well as their associated RF drivers play a major role in a wide range of applications due to their ability to manipulate light with high precision and high speed.
Exploring Light Manipulation with Acousto Optics
Acousto Optics (AO) in quantum computing are used to manipulate the properties of light such as its frequency, its intensity, its phase or even its position. These properties have been well exploited in various experiments involving entangled photons: the latest Nobel Physics prize 2022 has been awarded to such experiments where AO devices were used to switch the photons from one polarizer to another in order to determine their respective polarization state.
AO’s Role in Quantum computing revolution
AO was a good candidate due to its ability of deflecting the photons within tenths of ns. The entangled photons have led to major revolutions in the Quantum science and their application are numerous.AO devices can be used to manipulate the quantum states of the qubits, the basic units of quantum information. By controlling the phase or frequency of the lasers, AO enable precise state preparation. Additionally, AO can be used to direct the laser beams at individual qubits in the ion chain.
Quantum Communication: Harnessing AOMs for Secure Transmission
Quantum communication relies on the transmission of quantum states between distant locations. AOMs are used to modulate the characteristics of photons, enabling the creation of entangled states or encoding quantum information onto photons for transmission through optical fibers.
This modulation ensures the faithful transmission of quantum states, which is essential for applications like quantum key distribution (QKD) and quantum teleportation.
The role of acousto-optical devices in quantum sensing and metrology
Acousto-optic devices play a role in quantum sensing and metrology by enhancing the precision of measurements. By modulating the phase or frequency of laser beams used in interferometry setups, AOMs enable high-resolution measurements of physical quantities such as distance, time, and magnetic fields. These advancements have applications in gravitational wave detection, precision navigation, and quantum-enhanced imaging.
