Examples of new-generation optical device concepts using NP in a fiber core. (a) Quantum dot-based laser consisting in a NP-doped core region inside an optical cavity using Bragg gratings (BG). The pump light at any wavelength lower than the exciton wavelength can be guided in the inner cladding, interacting with the QD by leaking modes. (b) All-optical control of the properties of a Bragg grating containing periodic arrangement of NP.
