Parametric and cascaded parametric interactions in a quasiperiodic optical superlattice
Appl. Phys. Lett., Vol. 81, No.9, 26 July 2002,-0001,():
Quasi-phase-matching optical parametric and cascaded parametric processes in a two-component quasiperiodic superlattice were studied in theory and experiment. This letter demonstrates how to obtain red at 666nm and blue at 443 nm simultaneously from the superlattice using a 532nm laser as a pump through these two processes mentioned above. The result confirms that some nonlinear frequency conversion processes occurring in a high-dimension x(2) nonlinear photonic crystal may be efficiently achieved in such a one-dimension quasiperiodic optical superlattice.
