Abstract
An optical fiber includes a tubular glass cladding with a central opening filled with a colloidal solution of quantum dots in a support medium. The quantum dots may be caused to produce luminescence in response to input optical radiation, for example to produce optical amplification or laser radiation. A waveguide with an active medium comprising colloidal quantum dots is provided.
