The M-APE-I-1064-20 Intensity Modulator is designed for external modulation of 1064 nm laser up to 17 GHz or 20.5 Gb/s. It is also applicable for pulse generation for Ytterbium-Doped Fiber Amplifier amplification (YDFA) in satellite links and active mode locked laser applications. It is a bias-stabilized lithium modulator that proves to be extremely stable for long periods of time, and features excellent stability in a biased circuit, operating from 1030 to 1090 nm. It has an excellent operating temperature tolerance ranging from -30º to +75º C. The M-APE-I-1064-20 uses a Polarization Maintaining (PM) input and output fiber, featuring separate RF and bias ports.
