Electro-optical modulator R-AM

lithium niobate (LiNbO3)

ROF-AM 850nm lithium niobate optical intensity modulator uses an advanced proton exchange process, which has low insertion loss, high modulation bandwidth, low half-wave voltage, and other characteristics, mainly being used for space optical communication system, the cesium atomic time base, pulse generating devices, quantum optics, and other fields. Uses advanced proton exchange process, which has low insertion loss, high modulation bandwidth, low half-wave voltage, and other characteristics, mainly used for space optical communication system, the cesium atomic time base, pulse generating devices, quantum optics, and other fields. Application • Space optical communication system • Cesium atomic time base • Pulse generator • Quantum Optics Performance Maxim DC extinction ratio In this experiment, no RF signals were applied to the system. Pure DC extinciton has been measured. 1. Figure 5 demonstrates the optical power of modulator output, when modulator controlled at Peak point. It shows 3.71dBm in the diagram. 2. Figure 6 shows the optical power of modulator output, when modulator controlled at Null point. It shows -46.73dBm in the diagram. In real experiment, the value varies around -47dBm; and -46.73 is a stable value. 3. Therefore, the stable DC extinction ratio measured is 50.4dB.
