Dual Drive Externally Modulated Laser |
摘要 |
A method of generating a signal in an optical transmitter comprising a directly modulated laser and an amplitude modulator for modulating the output of the laser. The method comprises the steps of applying a first modulation signal representing data to be transmitted to the current of the laser such that the output frequency of the laser is modulated, and applying a second modulation signal representing the data to be transmitted to the amplitude modulator such that the amplitude of the laser output is modulated.
