Exail, a leading high-tech company specializing in the design and manufacturing of cutting-edge photonics components, launches its new low Vπ LiNbO₃ phase modulator, designed for high-power laser applications.

This new modulator, dedicated for Coherent Beam Combination (CBC) and Spectral Beam Combination (SBC), offers stability over time, temperature and vibration, while minimizing power consumption thanks to its ultra-low Vπ (up to 16 GHz). Specifically designed to handle up to 300 mW optical input at 1060 nm, this modulator is ideally suited for high-power lasers generation.

“We’ve developed a state-of-the-art modulator precisely designed for the rigorous demands of high-power lasers. Stability and efficiency were crucial factors in its meticulous design, addressing challenges related to energy consumption. The new low Vπ LiNbO₃ phase modulator stands out as a distinctive optical modulation solution, reshaping industry standards for stability, efficiency, and versatility. This modulator marks a revolutionary advancement in optical modulation, delivering unmatched results and specifications.” Says Nicolas Grossard, Product Manager at Exail.

Exail’s innovative low Vπ LiNbO₃ phase modulator excels in coherent beam combination, leveraging a single laser source with fine linewidth through multiple amplifications and precise phase modulators. In spectral beam combination, the modulator facilitates combining different laser power beams with distinct wavelengths, achieving uniform intensity distribution. Key optical features include an annealed proton exchange process, very low insertion loss (< 3 dB), high optical power handling (up to 300 mW), and stable performance over temperature and time. Notably, the Vπ of only 2 V @ 50 kHz minimizes RF and power consumption, while the device’s DC coupling option mitigates the RAM effect for optimal efficiency.

The new low Vπ LiNbO₃ phase modulator is also available at other wavelengths (O-band, C-band, 2 µm windows).
