Segmented waveguides in thin silicon-on-insulator [PDF]

, 2005
We have developed new silicon-on-insulator waveguide designs for simultaneously achieving both low-loss optical confinement and electrical contacts, and we present a design methodology based on calculating the Bloch modes of such segmented waveguides ...

Tunable optical properties of silicon-on-insulator photonic crystal slab structures [PDF]

Journal of the European Optical Society-Rapid Publications, 2009
A photonic crystal slab structure with one-dimensional periodicity, obtained by preferential etching of a silicon-on-insulator wafer, is numerically investigated in 3-D.

Highly-Sensitive Unbalanced MZI Gas Sensor Assisted With a Temperature-Reference Ring Resonator

IEEE Photonics Journal, 2022
In this paper we study the gas sensing performance of a compact silicon photonics Mach-Zehnder interferometer (MZI) with a coiled sensing arm. A partially exposed sensor was fabricated using deep UV lithography, with a process resolution of 248 nm ...

Compact focusing grating couplers for silicon-on-insulator integrated circuits [PDF]

, 2007
—We report experimental results on compact and broadband focusing grating couplers, both in silicon-on-insulator (SOI) and gold on SOI. An eight-fold length reduction of the coupling structure from fiber to photonic wire in SOI, as com-pared to a linear ...

Focused-ion-beam fabricated vertical fiber couplers on silicon-on-insulator waveguides [PDF]

, 2006
We fabricated grating couplers in silicon-on-insulator waveguides with focused-ion-beam. First devices were very lossy, but by using selective etchant and a hard mask we obtained efficiencies comparable to traditional fabrication ...
