With a research focus on integrated long-wavelength infrared (LWIR) photonics, I explore the untapped potential of quantum and nonlinear photonic technologies beyond traditional shorter wavelengths. My work emphasizes the critical applications of these technologies in sensing, both classical and non-classical. The unique properties of mid-infrared wavelengths allow for molecular fingerprinting, offering significant advancements in portable medical diagnostics. Additionally, longwave infrared LIDAR's ability to penetrate through challenging weather conditions and the noninvasive detection capabilities of terahertz radiation for complex molecules, such as explosives, highlight the transformative impact of extending photonic concepts to longer wavelengths. I am dedicated to not only advancing existing technologies but also leveraging these longer wavelengths to foster new conceptual breakthroughs in the field.
