The paper presents the modelling and design particularities of laterally-coupled distributed feedback lasers (LC-DFB), the fabrication process, involving a highly productive and cost-effective UV-nanoimprint lithography technique, and the characteristics obtained up to now for the LC-DFB lasers fabricated for pumping Cesium atomic clocks. 550 μm long LC-DFB lasers, emitting at 894 μm, had 10 mA threshold...
