SOA pulsed driver with nanosecond speed: a new fiber modulator

Semiconductor Optical Amplifiers (SOA) driven in pulse regime are a high dynamic range, lossless, high extinction ratio and highly polarizing fiber modulator solution available from 750 to 1700 nm.

It is a very compact unit optimized for single-shot to CW performance with pulse width lengths down to 1 nanosecond. This SOA pulsed driver delivers precision pulses which are generated internally by an on-board pulse generator, or on demand from an external TTL signal.

Semiconductor Optical Amplifiers driven in nanosecond pulse regime can be compared with AOMs, EOMs or direct laser diode modulators (see comparative table). It is the only solution meeting all the constraints for a reliable, stable and efficient fibered modulation.  

It is an ideal solution to drive most of the commercially available SOA like, for example, Innolume or Thorlabs. See our tutorial : fiber modulator basics

These products are now offered by AeroDIODE, Logo_aerodiodea new ALPhANOV spin-off company. The product manager is available to answer any technical of commercial question.

Complex systems, such as fiber lasers, can be quickly developed on this module platform.

Turn-Key solutions which include the SOA (Semiconductor Optical Amplifiers) are also offered by ALPhANOV as a SOM (Semiconductor Optical Modulator).
