Abstract : Quasi-phase-matched (QPM) second-harmonic generation (SHG) in periodically domain-inverted ferroelectric waveguides has been extensively studied in recent years for use in efficient frequency doubling of infrared radiation emitted from laser diodes. The period of the domain inversion is usually chosen to be A = mA/(2 (n1-n2), where A is the fundamental wavelength, m is the order of QPM, and n, and n2 are the effective indices of fundamental and second-harmonic waves, respectively. When the period is shortened to A = mA/(2 (n1+n2), the incident fundamental wave excites the second-harmonic wave propagating in the direction opposite to the fundamental wave. The feedback provided by the counter-propagation of the second-harmonic wave gives rise to the appearance of interesting properties such as bistability and switching in the output second-harmonic power. In this work we analyze numerically the dynamic properties of the contra-directional SHG in periodically domain-inverted structures.
