Research Perspective: Semiconductor Lasers – Optical Frequency Comb Sources | Nature
Optical frequency comb sources can emit perfectly periodic and coherent optical waveforms, and have rapidly evolved towards chip-level integration solutions. Two particularly important types are semiconductor Fabry-Pérot lasers and passive ring Kerr microresonators. Recently, Nikola Opačak, Benedikt Schwarz, and others from TU Wien in Austria published a paper in Nature, integrating these two technologies in … Read more
