| Popis: | Micro-ring lasers that exhibit a quality factor (Q) larger than 5.2 × 10{sup 6} with a direct-illumination, non-resonant pump are demonstrated. The micro-rings are coated with three organic dyes forming a cascaded energy-transfer, which reduces material-losses by a factor larger than 10{sup 4}, transforming incoherent light to coherent light with high quantum-efficiency. The operating principle is general and can enable fully integrated on-chip, high-Q micro-lasers. |
