Abstract:
A laser device comprising:a distributed feedback (DFB) laser section having two end faces extending substantially perpendicular to a major surface of the device, the DFB laser section producing laser radiation with a front emission direction at a first angle with respect to the two end faces, a modulator section with a modulator having a first end face abutting the end face of the DFB laser section having the front emission direction and a second end face being cut at a second angle with respect to the major surface of the device, wherein at least the modulator section has a reflective base, wherein the laser radiation is transmitted in the front emission direction from the DFB laser section to the modulator section through the end face of the DFB laser section having the front emission direction and the first end face of the modulator, with the laser radiation being modulated in the modulator and being reflected by the second end face towards the reflective base and further reflected by the reflective base towards the major surface of the modulator section, thereby forming a modulatable surface-emitting laser device.
