CW-THz vector spectroscopy and imaging system based on 155-µm fiber-optics

On-Chip THz Spectroscopy System

The research report presents the chip-scale solutions for THz spectroscopy applications. On the transmitter side, the architecture achieves dynamic waveform shaping of THz periodic waveform in free space by allowing interference of radiated electromagnetic-fields with rich harmonic components and proper delays at far field. On the receiver side, the electromagnetic interface between the on-chip...

Nonlinear Fiber Optics for Bio-Imaging

Two-photon excitation (TPE) is a modern technology with applications in microscopy and spectroscopy that has gained a great amount of attention in recent years. This technique is the best suitable to analyze thick tissues and live animals as it works in the near-infrared (NIR) region. In this work we implement and evaluate a two-photon setup that allows the shifting of the working wavelength ov...

Accuracy and resolution of THz reflection spectroscopy for medical imaging.

The use of THz radiation as a potential tool for medical imaging is of increasing interest. In this paper three methods of analysis of THz spectroscopic information for diagnosis of tissue pathologies at THz frequencies are presented. The frequency-dependent absorption coefficients, refractive indices and Debye relaxation times of pure water and pure lipids were measured and used as prior knowl...
