چکیده
We report a high-responsive hot-electron photodetector based on the integration of an Au–MoS 2 junction with silicon nitride microring resonator (MRR) for detecting telecom-band light. The coupling evanescent field MRR Schottky region enhances injection efficiency. device exhibits high responsivity 154.6 mA W −1 at wavelength 1516 nm, and moderately uniform responsivities are obtained over range 1500–1630 nm. This MRR-enhanced MoS offers possibilities integrated optoelectronic systems.

متن کاملVertical p-i-n germanium photodetector with high external responsivity integrated with large core Si waveguides.
We report a vertical p-i-n thin-film germanium photodetector integrated on 3microm thick large core silicon-on-insulator (SOI) waveguides. The device demonstrates very high external responsivity due to the low fiber coupling loss to the large core waveguides. The germanium width and thickness are carefully designed to achieve high responsivity yet retain high-speed performance. Even with fiber ...

Graphene is attractive for realizing optoelectronic devices, including photodetectors because of the unique advantages. It can easily co-work with other semiconductors to form a Schottky junction, in which the photo-carrier generated by light absorption in the semiconductor might be transported to the graphene layer efficiently by the build-in field. It changes the graphene conduction greatly a...
متن کاملVertically Coupled Microring Resonator Filter for Integrated Add/Drop Node
The add/drop wavelength filter is an essential component in the new-generation photonic network. Microring resonator filters using high index contrast (HIC) optical waveguides are recently attracting attention as add/drop filters owing to their compactness, functionality such as dispersion compensation, and ease of filter synthesis. In particular, the vertically coupled microring resonator (VCM...
متن کاملMultiple-wavelength integrated photonic networks based on microring resonator devices
Microring resonator devices implemented on silicon and silicon-on-insulator substrates have a unique potential to be used in high-bandwidth multiplewavelength integrated photonic networks. A scheme for the wavelength allocation is proposed, and its feasibility is verified experimentally. The important system-level trade-offs that result from the proposed scheme, including those among bandwidth,...
