Towards low loss non-volatile phase change materials in mid index waveguides
Joaquin Faneca, Ioannis Zeimpekis, S. T. Ilie +4
Photonic integrated circuits currently use platform intrinsic thermo-optic and electro-optic effects to implement dynamic functions such as switching, modulation and other processi…
Si-rich silicon-nitride waveguides for optical transmissions and towards wavelength conversion around 2 m
Manon Lamy, Christophe Finot, Alexandre Parriaux +6
We show that subwavelength silicon-rich nitride waveguides efficiently sustain high-speed transmissions at 2 m. We report the transmission of a 10 Gbit/s signal over 3.5 cm with…
Scattering of a plasmonic nanoantenna embedded in a silicon waveguide
Marta Castro-Lopez, Nuno de Sousa, Antonio Garcia-Martin +2
Plasmonic antennas integrated on silicon devices have large and yet unexplored potential for controlling and routing light signals. Here, we present theoretical calculations of a h…
Ultrafast Photomodulation Spectroscopy: a device-level tool for characterizing the flow of light in integrated photonic circuits
Roman Bruck, Ben Mills, David J. Thomson +4
Advances in silicon photonics have resulted in rapidly increasing complexity of integrated circuits. New methods are desirable that allow direct characterization of individual opti…
Optical absorption in highly-strained Ge/SiGe quantum wells: the role of Γ-to-Δ scattering
L. Lever, Z. Ikonić, A. Valavanis +7
We report the observation of the quantum-confined Stark effect in Ge/SiGe multiple quantum well heterostructures grown on Si(0.22)Ge(0.78) virtual substrates. The large compressive…
