Fiber modulator: a high speed intensity modulator and optical switch
This fiber modulator is a lossless, low noise, high speed (nanosecond), high dynamic range, high extinction ratio solution available from 750 to 1700 nm.
It is a very compact SOA-based unit optimized for single-shot to CW performance with pulse width down to 1 nanosecond. This fiber 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. It is the only solution meeting all the constraints for a reliable, stable and efficient fibered intensity modulation.
These products are now offered by AeroDIODE, a new ALPhANOV spin-off company. The product manager is available to answer any technical of commercial question.
