Tunable Laser Array Features Micromirror
Dec 1, 2002 — Santur Corp. of Fremont, Calif., has developed a tunable laser module in which an external microelectromechanical tilt mirror, rather than a relatively lossy combiner, selects the distributed feedback. The mirror enables control of optical coupling through an electronic feedback loop and offers a passively aligned package, potentially reducing costs. Furthermore, because no semiconductor optical amplifier is needed to make up for the combiner, it allows production of a simpler chip.
