Accurate, fast, adjustable wavelength selector

The Acousto-optic tunable filters (AOTF) are solid-state, electronically addressable, and random-access optical bandpass filters. Diffraction occurs when the acoustic beam and the light beam satisfy specific matching conditions. It can be used to quickly and dynamically select specific wavelengths from a wide spectrum.

CASTECH have designed AOTF products based on TeO2 slow shear waves according to the existing material properties, achieving optimal performance in each wavelength range and meeting most applications: operating wavelength of 400-1450 nm, resolution as low as 3 nm, and effective aperture up to 10 mm. In most cases, AOTFs are designed with a non-collinear structure, and randomly polarized input light passing through the AOTF will diffract two orthogonal polarizations of ±1 order that match the specific frequency of the ultrasonic wave. Users can easily use it and can be fiber-coupled as needed.

To achieve the best fit performance, it is recommended to use our RF drivers, which include fixed-frequency and variable-frequency series.

 

Applications:

●Spectral polarization

●Hyperspectral imaging

●Wavelength selection

●Optical communication

●Laser wavelength tuning

CASTECH's products are produced independently throughout the entire process and can be customized according to customer needs. Refer to the following list for standard products.
