Agiltron’s Free-space Electro-optic modulator(FEOM) is an easy-to-use tool to modify the phase, polarization, or amplitude of a free-space laser covering a wide wavelength range. For general applications, the device uses a pair of compensated LiNbO3 crystals. For high-power and short-wavelength applications, the device uses a special crystal pair to overcome LiNbO3 instability. The device should be driven by applying ± alternative high voltage to avoid internal charge build-up.
We provide driving electronics with modulation ranges from DC to MHz; the modulation depth is related to frequency due to limited amplification power.
Polarization cubes can be aligned and installed at both input and output ports to form an intensity modulator.
For amplitude modulation, polarized light is essential because the modulation process relies on controlling the intensity of light based on its polarization state. By incorporating input and output polarizers, the extinction ratio (ER) of the device is significantly improved.
