Acousto-optical Illumination Modules

L3Harris is leveraging more than 40 years’ experience in developing acousto-optic (AO) devices and technologies to design illumination modules that control the quantum states of trapped ions with extreme precision. With their low-noise, low-drift, and low-cross-talk capabilities, these subsystems are now enabling precision multi-channel optical beam control operations needed for quantum computing; quantum state manipulation for applications such as atomic clocks and advanced quantum sensing; and enhanced micromachining.

L3Harris Illumination Modules

Our internal research and development efforts and collaborative work with the University of Maryland and Duke University resulted in the first experimental system that supports up to 32 quantum bit (qubit) photonic-controlled ion-trap quantum computing with our multi-channel AO illumination module. This robust multi-channel AO illumination module provides the capability for using AO technology to perform the multi-qubit entangling operations and error correction needed for ion-trap based quantum computing and quantum state manipulation.

Our 32-channel AO modulators (AOMs) require a single 355 nm beam input and output 32 channels of individually modulated 355 nm light. The stable base mount assembly offers precision opto-mechanical alignment with input adjustment. Other wavelengths are also supported with some customization of components.

The modules also include optional auto input alignment, a 355 nm diffractive optical element, transform telescope for tele-centric input of 32 beams into the modulator, and a timing and Bragg adjusted AOM with 32 AOM modulated beams output. Purge covers are also provided to prevent dust and particle contamination by continuous flow of dry nitrogen or dry air. Optional RF drivers allow programmed switching of the radio frequency (RF) channels to the 32-channel RF drivers.

L3Harris Capabilities

L3Harris performs all AO research, design, development and testing of new solutions in-house. With a heavy investment in state-of-the-art optical communications and electronic equipment, we have the right tools for the job. Our facilities feature 10 optics laboratories, three electronic laboratories, and over 4,000 square feet of optical component fabrication facilities enabling grinding, polishing, optical surface metrology, vacuum-deposition, reactive-ion milling and bonding, and high-precision, specialty machining.
