Photonics and Electronics Research Lab

Ultra-fast Instrumentation Systems

With the emergence of wireless and medical bionics and imaging applications that exploit higher frequencies of the electromagnetic spectrum, non-invasive precise measurement of electric fields are paramount for engineers and designers of such systems.

This research area aims to study and design novel systems with significantly improved sensitivities, high resolution and non-invasive techniques incorporating electronics and photonics technologies, capable of measuring relatively weak electric fields over ultra-wideband of frequencies with enhanced accuracy and spatial resolution.

Emerging applications such as wireless communications, medical bionics and medical imaging are being developed to exploit higher frequencies of the electromagnetic spectrum, with non-invasive methods for precise measurement of electric fields becoming paramount for engineers and designers of such systems. With recent advances in photonics, it is possible to conceive novel systems with significantly improved sensitivities over the presently available methods. The primary aim of this project is to develop novel high resolution non-invasive electro-optic techniques capable of measuring relatively weak electric fields with an ultra-wideband of frequencies with greater spatial resolution and enhanced accuracy.
