This project proposes a new broadband, high-power, laser technology for THz sensing. This semiconductor laser based THz technology is crucial for a wide range of applications requiring the acquisition of THz spectral signatures of materials and high-frame rate hyper-spectral THz imaging. We propose two pathways to engineer this novel THz technology: using a tuneable, coupled-cavity quantum cascade semiconductor laser and by creating the broad emission spectra through active mode locking in a THz semiconductor laser. The THz laser coupled with the self-detection technique is the key to realising this, and will be explored both in model and experiment.Read moreRead less
Interaction of light with tissues: A hyper-spectral approach . This project aims to address an important problem of noncontact assessment of tissue including skin and cartilage. By using extremely wide spectrum – between the terahertz and the near infrared – the effects of scattering and absorption arising from the variation of tissue properties from macro- to nano-scale will be explored. Spatial variations of tissue properties will be addressed in model and experiment by combining spectroscopy ....Interaction of light with tissues: A hyper-spectral approach . This project aims to address an important problem of noncontact assessment of tissue including skin and cartilage. By using extremely wide spectrum – between the terahertz and the near infrared – the effects of scattering and absorption arising from the variation of tissue properties from macro- to nano-scale will be explored. Spatial variations of tissue properties will be addressed in model and experiment by combining spectroscopy with the novel terahertz and mid-infrared Scanning Near field Optical Microscopy. The outcomes will advance fundamental understanding of light interaction with multi-layered tissues. This will provide a tool for advancing bioengineering research, terahertz technology, and development in biomedical devices.Read moreRead less
