SKU: AOM4

The AOMF4 Series Fiber-Optic Acousto-Optic Modulators provide high-performance optical intensity modulation and frequency shifting with DC-15 MHz modulation bandwidth, low insertion loss (~1.2 dB), high extinction ratio (>55 dB), high polarization extinction ratio (>30 dB), and optical power handling up to 10 W — performance unmatched by other vendors. The device operates by driving a side-mounted piezoelectric transducer with a fixed 40 MHz carrier, creating a resonance induced acoustic grating within the TeO2 crystal. The output fiber is aligned to collect the first-order diffracted beam at the Bragg angle. An external driver varies the acoustic amplitude through an SMA control input, modulating the RF intensity, thus the optical attenuation. Rise and fall times are determined by the beam diameter, with smaller beams enabling faster response. Available for wavelengths from 1310 to 1620 nm and compatible with all fiber types, including SM, PM, and MM. The AOMF Series offers positive frequency shifting as standard, with negative-shift options available. Its epoxy-free crystal path and precision fiber collimators ensure excellent long-term stability and reliability.

Warning: The device needs to be mounted on a heat sink or on a metal frame
