OPTICAL FIBRE WITH QUANTUM DOTS

摘要

An optical fibre comprises a tubular glass cladding (1) with a central openi ng (2), filled with a colloidal solution of quantum dots (4) in a support mediu m (3). The quantum dots may be caused to produce luminescence in response to input optical radiation, for example to produce optical amplification or las er radiation. A waveguide with an active medium comprising colloidal quantum do ts is claimed.
