WebJun 1, 2015 · In this case, modulated corrugation pitch is employed in DFB lasers. Modulated corrugation pitch has a distributed phase shift in the center part, and therefore, the abrupt phase change at the center point can be avoided, leading to flatter distribution of the intra-cavity optical field [12]. Though the concept was proposed and theoretically ... WebAbstract: A spectral linewidth of 56 kHz is achieved by a CPM-MQW-DFB (corrugation-pitch-modulated multiquantum-well distributed feedback) laser at an output power of 25 mW. To separate effects of the white noise and 1/f noise in limiting the linewidth, the authors measured the delayed-heterodyne lineshape by using a short delay-fiber.
