Where to Buy Variable Optical Attenuators
Some applications, for example in optical fiber communications, need variable optical attenuators. There are both bulk-optical (free-space) attenuators and fiber-optic devices, based on different operation principles. They can vary in terms of polarization dependence, range and accuracy of attenuation, range of operation wavelengths, power handling capability and other properties.

| Company | Product Description |
 Rue François Mitterrand Institut d'Optique d'Aquitaine 33400 Talence France |  AeroDIODE has developed the variable optical attenuator – a high-speed intensity modulator and optical switch based on a semiconductor optical amplifier (SOA). It is available over a wide wavelength range from 750 to 1650 nm. Key features are high speed (down to 1 ns rise/fall time), high dynamic range (>48 dB), high extinction ratio (>50 dB) and an easy to use graphical user interface with multiple software libraries (LabVIEW, Python etc.). AeroDIODE also offers the semiconductor optical amplifier alone or the SOA driver in either CW or pulsed configuration. AeroDIODE also offers a wide range of fiber coupled AOMs (Acousto Optic Modulators) with various types of digital (TTL) or analog RF drivers. See also our white paper/tutorial on fiber-coupled modulators. See us at CLEO 2024 in Charlotte, North Carolina, United States, May 7–9 (booth 219)! |
 Fraunhoferstr. 22 82152 Martinsried Germany DIN EN ISO 9001:2015, DIN EN ISO 14001:2015 |  AMS Technologies carries a broad range of variable fiber-optic attenuators (VOAs), for manual operation as well as driven by stepper motors, MEMS mirrors or shutters, or based on liquid crystals:

 Test. Measure. Solve. 12–14 Parkway Drive Auckland 0632 New Zealand |  Quantifi Photonics' offers a range of extremely compact, cost-effective variable optical attenuators designed for streamlined testing and characterization of optical communication systems and optical components. They provide fast attenuation speed with low insertion loss and built-in power monitoring, with fixed attenuation or constant output power modes and supports single-mode, multi-mode and polarization-maintaining fibres. |
 Home of high power optics and coatings Horster Str. 20 30826 Garbsen Germany ISO 9001:2015 |  LASEROPTIK can provide coatings for variable optical attenuators. One can change the transmission by tilting an edge filter, with highest transmission at normal incidence and typical operation for angles of incidence between 0° and 45°. |
