The AOTF2916L is part of Alpha & Omega’s line of high-performance, low-noise, high-speed acousto-optic modulators. This particular model has a wavelength range of 850nm to 1820nm, an extinction ratio of greater than 70dB, and a switching speed of 10MHz. The AOTF2916L also has an aperture size of 14mmx14mm and a center frequency of 70MHz to 85MHz, enabling it to be used in a wide variety of applications. The modulator uses an acousto-optic transducer composed of two electro-mechanical transducers, one of which generates an acoustic wave in response to an electrical input, which causes changes to the optical properties of the optic fiber or liquid crystal waveguide. The other transducer used is a common electrical transducer, allowing for tuning the operating frequency of the first one. Additionally, the AOTF2916L has a Digital-to-Analog Converter (DAC), allowing for fine control of the modulator’s operating frequency.
