Resonantly Enhanced Phase Modulator In Free Space

Electro-optic phase modulator (PM) alters the phase of an optical signal by utilizing an electric field on an electro-optic material. These can function across a broad spectral range, from ultraviolet (UV) to infrared (LWIR with minimal optical loss, high optical power, and modulation frequencies that range from 50 kHz to 20 GHz.

QUBIG provides Phase Modulator in bulk/free-space (PM), fiberoupled (PM.FC) and surface-mount (PM.S) devices, which are ideal for applications such as laser cooling, spectroscopy, and spectral broadening due to their ability to achieve high modulation depths with low driving voltages
