Integrated blue laser and optical frequency comb for the next generation of lattice clocks
Abstract
The proposed project will develop a laser platform that pairs the high-power-gain Gallium Nitride (GaN) medium with low-loss Silicon Nitride (Si3N4) technology in the blue wavelength range. We will a combine GaN blue laser with a Si3N4 integrated microresonator to achieve the reduction of the laser linewidth and simultaneously the generation of the optical frequency comb. The unique expertise will enable EPFL to develop integrated lasers in the visible range that directly target atomic clock transitions, thereby contributing a key core technology for future compact portable lattice clocks.
