nitttrchd.ac.inThe structure builds a one-dimensional interference grating (Bragg Scattering) and the grating provides optical feedback for the laser. DFB laser diodes do not use two discrete mirrors to form the optical cavity (as they are used in conventional laser designs). The grating acts as the wavelength selective element for at least one of
Chapter Quantum Confinement Effect of 2D Nanomaterials
cdn.intechopen.comwire (nanowire) confines in two dimensions; and a quantum well confines only in one dimension. The corresponding structures are also termed as zero-dimensional (0D), one-dimensional (1D), and two-dimensional (2D) potential wells, respec-tively, with regard to the number of dimensions in which the confined particle has freedom of movement.
