“Spatial optical solitons in nematic liquid crystals: en-route to photonics”


We present an overview of the main features of nematicons, optical spatial solitons governed by  reorientation in nematic liquid crystals. Based on their guiding properties and nonlocality, nematicons exhibit a number of intriguing effects in nonlinear optics with potential applications in photonics, including long-range attraction, controlled refraction and reflection, cavity-less bistability, guided-wave devices, soliton-assisted random lasing.
