Abstract

Coherent blue-light emitters are currently of great practical interest because of their potential use in high-density optical-data-storage and multicolor-display applications. Second-harmonic generation of blue light by the nonlinear interaction of fundamental electric fields in III–V heterostructure waveguides oriented in the [001] crystal direction has been demonstrated.¹ For the [001] direction, the crystal symmetry is such that one of the counterpropagating fields must be a transverse electric (TE) field and the other must be a transverse magnetic (TM) field for the nonlinear interaction to cause second-harmonic generation.
