Enhanced third harmonic generation in periodic structures

Pramana (Impact Factor: 0.65). 10/1996; 47(4):317-324. DOI: 10.1007/BF02848531


We consider third harmonic generation in a periodic layered medium with alternate nonlinear media. We show enhanced third
harmonic generation when the fundamental frequency matches one of the mode frequencies of the distributed feedback structure.
The observed feature is explained in terms of large local field enhancement for the fundamental wave.

    ABSTRACT: We study third harmonic generation in layered configuration when the fundamental exhibits bistable response. We consider two geometries, namely, a Fabry-Perot cavity with reflection coatings and a distributed feedback structure with alternate nonlinear layers. In both the cases for suitable choice of frequency, the power response at the fundamental frequency is bistable. We show that bistability of the fundamental leads to a multivalued character of the generated third harmonic in both the forward and backward directions. Moreover, we study frequency response in the case of the Fabry-Perot cavity and show that additional structures arise in the generated third harmonic due to frequency bistability of the fundamental. Our calculations suggest the possibility of an all optical switch at third harmonic frequency controlled by the parameters (like intensity, frequency) of the fundamental.

    ABSTRACT: We present large enhancement of the nonlinear wave mixing process (third-harmonic generation) in photonic-band-gap materials made of negative and positive index media, at the band edge of the zero-n[over ¯] band gap. Incorporating metamaterial-based, electromagnetically induced transparency (EIT)–like resonance in the nonlinear layer leads to unprecedented line narrowing of the generated third harmonic. This scheme permits the mapping of the narrow EIT resonance at the fundamental frequency to the generated third-harmonic frequency with even narrower line shape.
