High power CW DFB
Etern-laser's high-power DFB laser chip operates in a single mode under direct-current drive and achieves 70mW optical output over -5~70℃. It uses a buried heterojunction (BH) structure, offering a low threshold, high optical efficiency, symmetric far-field divergence, and high coupling efficiency. A special design enables high output power with a short cavity, effectively reducing product cost. The chip undergoes the full set of Telcordia GR-468 tests, and every chip passes stringent certification procedures before shipment to ensure high reliability.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
