SOA pulse modulation module
Product introduction
HC-PLM series SOA pulse modulation module uses a semiconductor optical amplifier (SOA) as a core converter device to achieve ultra-narrow pulse width optical pulse generation. Its characteristics of fast rise time, high pulse extinction ratio, good stability and convenient use make it an ideal choice to replace electro-optic and acousto-optic modulators in various optical fiber sensing systems. But also can be apply to that aspects of quantum communication system, semiconductor test, homodyne coherent detection and the like.
