Optical loss by surface transfer doping in silicon waveguides
Luca Alloatti, Christian Koos, Juerg Leuthold
We show that undoped silicon waveguides may suffer of up to 1.8 dB/cm free-carrier absorption caused by improper surface passivation. To verify the effects of free-carriers we appl…
Second-order nonlinear optical metamaterials: ABC-type nanolaminates
Luca Alloatti, Clemens Kieninger, Andreas Froelich +7
Structuring optical materials on a nanometer scale can lead to artificial effective media, or metamaterials, with strongly altered optical behavior. Metamaterials can provide a wid…
Photonics design tool for advanced CMOS nodes
Luca Alloatti, Mark Wade, Vladimir Stojanovic +2
Recently, the authors have demonstrated large-scale integrated systems with several million transistors and hundreds of photonic elements. Yielding such large-scale integrated syst…
