Abstract
We investigate theoretically the possibilities of simultaneous laser generation in all, closely spaced modes of chirped photonic crystals layer in all visible region of the spectrum both for chirped rugate and chirped stratified photonic crystals. The spectra of reflection, field localization as well as relative photonic density of states and absorption for both rugate and stratified photonic crystals with different chirping parameters, as well as for a Fabry-Perot resonator are computed and compared. It was shown that there are two kinds of modes in chirped photonic crystals: edge modes and bound modes. We also calculated the threshold values for mentioned structures. In addition, we note that with the ability to control the chirp contrast, it becomes possible to obtain a white laser with a simple system on a chip, which can find wide application ranging from miniaturized coherent light source, optical sensing, to visible light communication.
