Buying Optical Modulators
Optical modulators modify light properties, controlled with electrical signals. They can modulate optical power, intensity, and phase, essential for various communication and measurement applications.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

![]() Rue François Mitterrand Institut d'Optique d'Aquitaine 33400 Talence France See us at CLEO 2025 in Long Beach (CA), USA, May 4–9 (booth 327)! | ![]() AeroDIODE has developed the fiber modulator – 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. Product-specific web page |
