Open AccessSwelling-Based Chemical Sensing With Unmodified Optical Fibers
We use distributed fiber optic strain sensing to examine swelling of the fiber’s polymer coating. The distributed sensing technique that uses unmodified low-cost telecom fibers opens a new dimension of applica...

Open AccessRealization of a polarization-insensitive optical frequency-domain reflectometer using an I/Q homodyne detection
We report on the development and implementation of an optical frequency-domain reflectometer (OFDR) sensing platform. OFDR allows to measure changes in strain and temperature using optical fibers with a length...

A Holistic Approach Towards Peer-to-Peer Security and Why Proof of Work Won’t Do
Separation of identity and location is one of the key properties of peer-to-peer networks. However, this separation can be abused to mount attacks against the network itself. Our contribution in this matter is...
