Method and apparatus for reduction of electrical cross-talk and wave length chirp in a distributed bragg reflector laser

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.
