Other Abstract

The realization of a one-dimensional (1D) random laser (RL) by using artificially fabricated scatterers is reported in this letter, and the lasing characteristic has also been investigated comprehensively. The manipulation of the lasing mode in the 1D microwire (MW) RL can be achieved through micro-pits prepared by the laserablation technique. Well-defined sharp lasing peaks were realized based on the coherence feedback process in the 1D optical waveguide. The near-and far-field images exhibit excellent spatial intensity distribution, and the stability of lasing modes has also been investigated. Our results represent a novel method towards the development of a manipulated-RL, which will highlight the application of disordered systems in optoelectronic devices.
