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 ...

Silicon-on-insulator nanophotonics [PDF]

SPIE Proceedings, 2005
Nanophotonics promise a dramatic scale reduction compared to contemporary photonic components. This allows the integration of many functions onto a chip. Silicon-on-insulator (SOI) is an ideal material for nanophotonics. It consists of a thin layer of silicon on top of an oxide buffer.

An electret-based pressure sensitive MOS transistor [PDF]

, 1988
The operation of the MOSFET is based on the fact that the lateral conductivity of silicon at the silicon-dioxide-silicon interface strongly depends on the transverse electric field in the oxide. Adding a small air-filled spacer between the metal gate and

Preparation of a Photoluminescent Film on a Silicon-On-Insulator Device for the Simple, Rapid, and Quantitative Detection of a Hydatid Disease Diagnostic Protein Marker

IEEE Photonics Journal, 2017
A silicon-on-insulator (SOI) device is an important integrated circuit technology containing an insulating material. In this paper, an SOI wafer consisting of n-type silicon grown on the surface of a SiO2 layer was adopted.

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 ...
