Architecture for integrated RF photonic downconversion of electronic signals

Electronic analog to digital converters (ADCs) are run-ning up against the well-known bit depth versus bandwidth trade off. Towards this end, radio frequency (RF) photonic-enhanced ADCs have been the subject of interest for some time. Optical frequency com ...

Aptamer-field-effect transistors for small-molecule sensing in complex environments

Nako Nakatsuka

Aptamer-functionalized field-effect transistor (FET) biosensors enable detection of small-molecule targets in complex environments such as tissue and blood. Conventional FET-based platforms suffer from Debye screening in high ionic strength physiological e ...

Understanding delayed fluorescence and triplet decays of Protoporphyrin IX under hypoxic conditions

Georges Wagnières

Photosensitizers of singlet oxygen exhibit three main types of reverse intersystem-crossing (RISC): thermally activated, triplet-triplet annihilation, and singlet oxygen feedback. RISC can be followed by delayed fluorescence (DF) emission, which can provid ...

Parameter Estimation with GNSS-Reflectometry and GNSS Synthetic Aperture Techniques

Miguel Angel Ribot Sanfelix

Aside from intentional interference, multipath is the most significant error source for Global Navigation Satellite Systems (GNSS) receivers in many operational scenarios. In this thesis, we study the multipath estimation from two different perspectives: t ...
