Sevensix introduces frush optical frequency comb generator in U.S. market

Sevensix Inc., based in Minato-ku, Tokyo, announced on May 30, 2025, the launch of its optical frequency comb generator, Frush, in the U.S. market, starting October 2025. The platform generates optical frequency combs for applications in optical communications, quantum optics, and precision spectroscopy.
Frush uses a single dual-drive Mach-Zehnder modulator and an auto-bias control system, producing a stable optical frequency comb spectrum within 10 seconds of startup. It integrates with external narrow-linewidth lasers and RF signal generators, allowing users to utilize existing equipment and switch signal sources based on application needs. The system supports spectrum broadening to tens of nanometers and pulse compression to sub-picosecond durations when paired with a high-power EDFA and nonlinear optical fiber. It also enables phase-locking of two lasers separated by approximately 300 GHz, with various upgrades available.
Specifications include a center wavelength of 1550 ± 20 nm, a -20 dB spectral width greater than 200 GHz, average output power above -5 dBm at 13 dBm input, pulse duration of 6 ps or less when compressed, comb spacing of 12 to 18 GHz (fixed at factory), FC/APC fiber ports, and linear polarization capability. The device measures 148×480×430 mm.
