EOM phase modulator refers to an Electro-Optic Modulator that is used to modulate the phase of the optical wave without affecting its amplitude or polarization. It’s commonly used in laser systems, telecommunications, and precision measurement systems like interferometers.

key components:

• Crystal Material: Lithium niobate (LiNbO₃) and other electro-optic materials are often used.

• Electric Field Control: An external voltage is applied to create the electric field, controlling the phase shift of the light.

• Frequency Ranges: EOM phase modulators can operate across a wide range of frequencies, from MHz to GHz, making them suitable for high-speed applications.
