Silicon photonics is the guiding of light in a planar arrangement of silicon-based materials to
perform various functions. We focus here on the use of silicon photonics to create …

We have designed a high-efficiency broadband grating coupler for coupling between silicon-
on-insulator (SOI) waveguides and optical fibers. The grating is only 13 µm long and 12 µm …

PECVD silicon nitride photonic wire waveguides have been fabricated in a CMOS pilot line.
Both clad and unclad single mode wire waveguides were measured at λ= 532, 780, and 900 …

We have designed and fabricated an out-of-plane coupler for butt-coupling from fiber to
compact planar waveguides. The coupler is based on a short second-order grating or …

We present high-efficiency grating couplers for coupling between a single-mode fiber and
nanophotonic waveguides, fabricated both in silicon-on-insulator (SOI) and InP membranes …

We demonstrate single-mode photonic wires in silicon-on-insulator with propagation loss as
low as 2.4 dB/cm, fabricated with deep ultraviolet lithography and dry etching. We have also …

The implementation and engineering of bright and coherent solid state quantum light
sources is key for the realization of both on chip and remote quantum networks. Despite …

The field of photonic crystals has, over the past few years, received dramatically increased
attention. Photonic crystals are artificially engineered structures that exhibit a periodic …

We prove that an adiabatic theorem generally holds for slow tapers in photonic crystals and
other strongly grated waveguides with arbitrary index modulation, exactly as in conventional …

Silicon photonics is rapidly gaining maturity in high-bandwidth optical communication, with
applications in datacom, access networks, and I/O for bandwidth-intensive electronics. Also …
