Single-Mode 638nm Red Pigtailed Laser
Fujin Optoelectronics offers various fiber-coupled semiconductor lasers covering 380nm~1600nm, with single-mode, multimode, and polarization-maintaining fibers. The source then names Fuxin Optoelectronics as holding multiple direct fiber-to-laser-chip coupling technologies. These achieve higher coupling efficiency without lens assemblies, shorten development, and provide faster, lower-cost customized solutions. Our vision is to enable fiber-coupled output whenever a TO laser diode is available on the market.

Ytterbium‑doped fiber serves as the core energy‑conversion component inside a fiber laser. Pump light emitted by laser diodes is coupled into the gain fiber, and energy is transferred to signal laser beams via ytterbium ion energy‑level transition for power amplification. Two dominant pump wavelengths, 915 nm and 976 nm, have been widely adopted over decades. With the rapid progress of pump chip and wavelength‑locking technology, 976 nm edge‑emitting laser (EEL) pumps have gradually surpassed the 915 nm route and become the new industry mainstream. Shenzhen Lemon Photonics Technology Co., Ltd keeps developing high‑performance pump chips for fiber laser manufacturers.
The 850 nm and 940 nm infrared narrow‑bandpass filters launched by Innovation Photoelectric are core optical components specially designed for day‑and‑night security cameras. They effectively eliminate image interference during visible‑light and infrared‑illumination switching, delivering stable round‑the‑clock monitoring performance.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
As fundamental refractive optical components, plano‑convex spherical lenses consist of one convex spherical surface and one flat surface.
