On-chip spectrometer using vertical hetero structure of long pass optical filters and silicon films

Yu Wang, Bedabrata Pain, Tom Cunningham and Xinyu Zheng

1. Novelty This art describes a ultra-lightweight, on-chip spectrometer capable of multi- wavelength imaging with high efficiency and narrow bandwidth.

Development of this capability directly relates to all current and future NASA efforts relevant to the multi-spectrum imaging and hyper-spectrum imaging for both remote sensing and in situ missions.

Circuit and Method of Communication Over DC Power Line
Circuit and Method of Communication Over DC Power Line hot!
Date added: 12/03/2007
This device moves computational, sensing, and actuation abilities closer to the source, allows for the networking of multiple like nodes to each other and to a central processor, and can do so using nothing more than the already in-situ power wiring of the system.
