Contribution

It introduces a novel theoretical approach for white laser generation using chirped photonic crystals with adjustable chirping contrast.

Findings

Potential for simultaneous multi-mode laser generation

Feasibility of on-chip white laser system

Control over laser spectrum through chirping contrast

Abstract

We report the results on theoretical investigation about possible simultaneous laser generation in all, closely spaced modes of chirped photonic crystals layer in all visible region of the spectrum. With the possible ability to control the chirping contrast, it allows to obtain a white laser with a simple system on a chip, which can find wide application.
