| 摘要 |
The embodiments of the invention provide an apparatus for optical spectral filtering and dispersion control for wavelength multiplexed laser sources using fiber Bragg gratings. More specifically, the apparatus includes a laser diode having a first end and a second end opposite the first end. The first end of the laser diode has a first semi-transparent portion; and, the second end of the laser diode has a second semi-transparent portion. The apparatus further includes an optical fiber connected to the second end of the laser diode. The optical fiber has a first end and a second end opposite the first end, wherein the first end of the optical fiber is connected to the second end of the laser diode. The laser diode comprises a laser cavity; and, the optical fiber comprises an extension of the laser cavity. Moreover, the second end of the optical fiber has a reflective surface.
