We propose a new all-planar technology scheme for coupling active gain or absorbing regions to low-propagation-loss, large-mode passive regions using monolIthic waveguides vertically directionally coupled wIth a grating in an antiresonant reflecting optical waveguide (ARROW) geometry. Basic aspects of the concept have been demonstrated by laser action in an InGaAsP/InP ARROW grown by hydride vapor phase epitaxy and optically pumped by a Nd:YAG laser. This is the first demonstration of interlayer vertical directional grating coupling in III-V wavegnides.
