It is a very compact SOA-based unit optimized for single-shot to CW performance with pulse width down to 1.5 nanosecond. This fiber optic modulator delivers precision pulses which are generated internally by an on-board pulse generator, or on-demand from an external TTL signal. SOM (Semiconductor Optical Modulator) can be compared with AOMs, EOMs or direct laser diode modulators. SOM maintain the narrow optical linewidth of an input CW signal while producing very short pulses. It is the only solution meeting all the constraints for a reliable, stable and efficient fiber-coupled intensity modulation.
