| Popis: | Optical solitons or soliton-like states shed light to blue-shifted frequencies through a resonant emission process. We predict a mechanism by which a second propagating mode is generated. This mode, called negative resonant radiation originates from the coupling of the soliton mode to the negative frequency branch of the dispersion relation. Measurements in both bulk media and photonic crystal fibres confirm our predictions. |
