• Provides low insertion loss (<3 dB) and high diffraction efficiency (>70%).
• Supports operation frequencies up to 200 MHz, ensuring high-speed modulation.

General Description

Photonics of Crystals (POC) Acousto-Optic Multi-Channel Modulators (AOMM) are advanced devices designed to modulate or deflect multiple optical beams simultaneously. By integrating transducer arrays into a single acousto-optic crystal, AOMMs significantly increase the number of modulated beams, reduce scanning rates, and lower modulation bandwidth, improving overall linearity and efficiency.

Compared to single-channel AOMs, AOMMs provide independent control of multiple beams or collimated light lines, making them ideal for demanding applications such as laser color printers, multi-channel acousto-optic spectrometers, optical digital computers, and video infrared image processing systems.

POC’s AOMMs are constructed using low-scatter fused quartz, crystalline quartz, and Tellurium Dioxide to ensure low insertion loss, high diffraction efficiency, and robustness under high-power conditions. These modulators support up to 10 channels and operate at frequencies up to 200 MHz, minimizing acoustic and electrical crosstalk while delivering precise performance.

General Applications and Examples

1. Laser Color Printing:
   AOMMs are integral to high-resolution laser color printers, providing simultaneous modulation of multiple beams to enable efficient and precise color printing processes.
2. Spectroscopy and Imaging:
   Multi-channel modulation enhances the performance of spectrometers and dynamic infrared imaging systems, enabling faster data acquisition and higher-quality image processing.
3. 2D Information Processing:
   AOMMs are used in optical computing systems to modulate multiple light beams for parallel data processing, improving computational speed and accuracy.
4. Material Processing:
   AOMMs enable simultaneous modulation of multiple laser beams for high-speed micromachining, marking, and welding applications, enhancing productivity and precision.
