摘要： A shunt capacitor is placed in parallel with the tuning section of a tunable electro-absorption modulated Distributed Bragg Reflector (DBR) laser. This reduces the electrical cross-talk between the modulator and tuning sections of the device. This reduction of electrical cross-talk results in a reduction of the wavelength chirp and therefore reduces the pulse distortion of a light wave traveling along an optical fiber.

摘要： In accordance with the invention, an optical communications system is provided with a light source comprising a semiconductor laser whose wavelength is locked by a spectrally selective element and whose output is simultaneously filtered by the same element. The result is a source output suitable for longer distance transmission and higher speed transmission. An exemplary embodiment using a fiber Bragg grating as the simultaneous selective element provides chirp reduction, increased extinction ratio andabsolute wavelength stability within 2 pm.
