Description

Semiconductor Optical Amplifiers (SOA amplifiers), when driven in pulse regime with our pulsed SOA driver become a high dynamic range fiber modulation solution available from 750 to 1700 nm. It is a lossless, high extinction ratio and potentially highly polarizing device. 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. SOA Amplifiers (Semiconductor Optical Amplifiers) driven in nanosecond pulse regime can be compared with AOMs, EOMs or direct laser diode modulators (see comparative table and our tutorial : fiber modulator basics). It is the only solution meeting all the constraints for a reliable, stable and efficient fiber modulation.
