Printed Nanolaser on Silicon
We
propose and demonstrate a direct integration of a wavelength-scale
III–V nanolaser onto a silicon-on-insulator (SOI) waveguide.
By employing high-precision microtransfer printing techniques, with
an optimally designed photonic crystal nanolaser structure, we experimentally
achieved a coupling efficiency of 83% between the InGaAsP nanobeam
laser and the SOI waveguide. Our III–V nanobeam laser is designed
as an asymmetric one-dimensional photonic crystal cavity, which allows
unidirectional coupling to the combined III–V nanobeam waveguide
with high efficiency. Through the compact vertical coupler in the
region where the III–V and SOI waveguides overlap at the optimal
length of 3.2 μm, 88% of the light from the printed III–V
nanolaser can theoretically be coupled to a vertically integrated
SOI waveguide
