Sevensix Inc., a Tokyo-based photonics technology company, officially launches its advanced optical frequency comb generator, Frush, in the United States, beginning October 2025. The move marks a strategic expansion into one of the world’s most demanding research and industrial markets.
Frush is a next-generation electro-optic (EO)-based optical comb generator designed for high-precision applications in optical communications, quantum optics, and spectroscopy. Notable for its simplicity and speed, Frush achieves stable frequency comb generation within 10 seconds of startup, making it highly suitable for both laboratory and industrial environments.
Built around a single dual-drive Mach-Zehnder modulator and Sevensix’s proprietary auto-bias control system, Frush offers users turnkey functionality. The system accommodates external narrow-linewidth lasers and RF signal generators, allowing easy integration into existing setups with minimal investment.
To support the U.S. rollout, Sevensix is partnering with a national distribution and technical support network aimed at delivering responsive, localized service. This approach is intended to meet the high operational standards of American engineers and researchers.
Frush also supports advanced capabilities, including spectral broadening using EDFA and nonlinear optical fiber, pulse compression to sub-picosecond durations, and laser phase-locking across a 300 GHz separation. It features a center wavelength of 1550 ± 20 nm, over 200 GHz spectral width, and comb spacing between 12 and 18 GHz.
