Abstract

It is provided a laser arrangement, having an electro-absorption-modulated laser, having a laser section and an electro-absorption modulator section; a current source for supplying the laser section with current; a DC voltage source that is arranged in addition to the current source and can be used to apply DC voltage to a diode structure of the electro-absorption modulator section; a driver with which an RF signal is able to be fed to the laser; and an electrical connection via which the driver is connected to the laser. The electrical connection provides a direct current connection between the driver and the laser such, and the driver is configured such, that a photocurrent that is generated in the electrode-absorption modulator section of the laser by illumination with light of the laser section at least partially flows to the driver and at least contributes to the energy supply of the driver.
