| Abstract | We report the fabrication of distributed feedback lasers in Rhodamin 6G doped SU-8 by direct femtosecond laser writing. The devices are fabricated by point-by-point exposure and consist of a core layer with a low-order Bragg grating on the surface. A quarter-wavelength phase shift is introduced in the middle of the grating section to obtain single-mode emission. Lasing at different wavelengths is demonstrated by changing the grating pitch. Spectral emission, threshold and lifetime characterization is performed by pumping the laser with a pulsed, frequency double Nd:YAG laser. |
