General Description
Photonics of Crystals (POC) Acousto-Optic Tunable Filters (AOTF) are advanced solid-state, electronically addressable devices designed for dynamic and selective wavelength tuning. AOTFs operate as bandpass filters, exploiting diffraction effects to isolate specific wavelengths when the acoustic beam and light beam meet precise matching conditions. This capability makes AOTFs ideal for applications requiring quick and precise wavelength adjustments across a wide spectrum.
Our AOTFs are crafted with Tellurium Dioxide (TeO2) to optimize performance for specific wavelength ranges, offering an operational span from 400 nm to 1450 nm. Featuring resolutions as fine as 3 nm and an effective aperture of up to 10 mm, POC’s AOTFs achieve excellent tuning precision. The non-collinear architecture supports the diffraction of two orthogonal polarizations, providing robust functionality for polarized and randomly polarized light. These devices can also be fiber-coupled for enhanced usability.
For optimal operation, POC recommends the use of our RF drivers, available in fixed-frequency and variable-frequency configurations, tailored to meet diverse application needs.
General Applications and Examples
- Spectral Polarization:
AOTFs enable accurate spectral separation and polarization analysis, making them indispensable in optical systems requiring precise control of wavelength and polarization. - Hyperspectral Imaging:
AOTFs play a key role in hyperspectral imaging, allowing rapid scanning across multiple wavelengths for environmental monitoring, biomedical imaging, and material analysis. - Optical Communication:
In optical communication systems, AOTFs are used for wavelength routing and signal management, ensuring high-speed and interference-free data transmission. - Laser Wavelength Tuning:
AOTFs facilitate rapid tuning of laser wavelengths, supporting advanced research in spectroscopy and optical diagnostics.
