Abstract
The analysis of light propagation, diffraction and amplification in active multilayer corrugated waveguides with incorporated nonharmonic relief gratings, carried out by Rayleigh-Fourier formalism, is presented. On the base of this theoretical analysis the new possibilities of biharmonic grating for the design of single-frequency DFB lasers are discussed. The lasing characteristics of DFB heterolasers with biharmonic resonator are determined. It is shown that the biharmonic resonator with phase shift pi and space-modulated coupling coefficiency is capable of providing stable single-frequency oscillation at Bragg wavelength. The three-beam maskless holographic method for the fabrication of submicron biharmonic relief structures on the surface of n- AIIIBV semiconductors is developed. The biharmonic structure of period d equals 0.5 micrometer, possessing phase shift pi, is fabricated on n-InP in the process of laser-induced maskless wet photochemical etching under action of three Ar+ laser beams.
