EOM electro-optical modulators with fiber optics

EOMs are capable of modulation and switching tasks (amplitude and phase modulation, generation of sidebands).The EOM described here was specially designed for high quality phase modulation.

Schäfter+Kirchhoff offers polarization-maintaining fiberoptic components that are ideally suited for an implementation of an EOM in a measurement setup. Upgrading to fiber-optics enhances laser safety by confining the beam to optical fibers and increases the stability and reproducibility of measurement setups compared to free-beam breadboard constructions.

The EOMs described here are manufactured by qubig and are designed for the modulation of the optical phase.
