Analysis of Leakage Loss in Silicon Photonics with Finite Gain Compensation

open access: yesIEEE Photonics Journal, 2017
Silicon waveguides fabricated on silicon-on-insulator wafers are leaky in nature. This fact puts a lower bound on the insulator thickness in silicon photonic structures as integrated with compact electronic devices.

Tapered photonic crystal microcavities embedded in photonic wire waveguides with large resonance quality-factor and high transmission [PDF]

open access: yes, 2008
We present the design, fabrication, and characterization of a microcavity that exhibits simultaneously high transmission and large resonance quality-factor (Q-factor). This microcavity is formed by a single-row photonic crystal (PhC) embedded in a 500-nm-

Investigation on a novel SiC Schottky barrier diode hydrogen sensor with trench-insulator structure

open access: yesMaterials Research Express, 2021
A novel SiC Schottky barrier diode (SBD) hydrogen gas sensor with trench-insulator structure was proposed in this paper. A physical model is built for this hydrogen sensor based on 4H-SiC SBD thermionic emission theory, tunneling effect of carriers ...

Nanoribbon Biosensor-Based Detection of microRNA Markers of Prostate Cancer

open access: yesSensors, 2023
Prostate cancer (PC) is one of the major causes of death among elderly men. PC is often diagnosed later in progression due to asymptomatic early stages. Early detection of PC is thus crucial for effective PC treatment.

Silicon-on-insulator nanophotonics [PDF]

open access: yesSPIE 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.
