Abstract

We present a lateral tunnel epitaxy technique to grow InP membranes atop silicon waveguides on silicon-on-insulator substrates. Uniform InP membranes extending hundreds of micrometers in length can be achieved. Room temperature optically pumped lasing was also realized, showcasing the excellent crystal quality.
