Abstract
The scattering properties of structures with periodicities in the optical wavelength scale have been widely employed to control the light propagation and generation of thin luminescent films. An example of the control on radiative properties of thin films through periodic modulations is the well known DFB (Distributed FeedBack) laser. Such devices consist of layers exhibiting a periodical modulation of their optical constants (refractive index and/or gain) which enable controlled modification of light emission and propagation resulting in lasing without mirrors. Light propagation and generation is then modified following interaction with the resulting waveguide grating.
