A combination of circular and elliptical air holes results are employed, resulting in a very low material absorption loss of 0.045 cm-1 atDcore = 450 µm and f = 1 THz. A flat dispersion of 0.73 ± 0.13 ps/THz/cm is obtained for a broad frequency range of 0.5–1.4 THz. Core diameter and frequency response of other key features such as normalized frequency (V-parameter), confinement loss, effective area, nonlinearity and the percentage of the power flow through different sections of the proposed PC-PCF are also analyzed. Comparing to state-of-the-art, our design is superior in terms of loss, dispersion and power fraction. Our proposed design can be manufactured using the established extrusion process and be used for long distance low-loss Terahertz (THz) communication.}, journal={RESULTS IN OPTICS}, author={Sadath, Md Anwar and Kokinda, Jacob and Lin, Dayang and Hossain, Md Sanwar and Gu, Qing}, year={2024}, month={May} }

The main challenge in perovskite photodetectors (PSPDs) is to achieve high responsivity and fast speed simultaneously. In this work, this challenge is overcome by employing a directly patterned nanograting methylammonium lead iodide (MAPbI 3 ) film in metal‐semiconductor‐metal (MSM) PSPD on interdigitated indium tin oxide (ITO) electrodes. Because of the improved perovskite morphology after directly patterning by nanoimprint lithography, as well as the enhanced electric field intensity by the perovskite nanograting and interdigitated electrodes, the PSPDs have responsivity of 441 A W −1 , detectivity of 8.32 × 10 12 Jones, response time of 10.7 µs, all of which are among the best performances in MSM PSPDs. Moreover, the PSPDs maintain excellent photocurrent performance after 20 days of air exposure. The approach opens a path to manufacturing‐friendly, high‐performance, and reliable PSPDs and paves the way toward perovskite‐based optoelectronic circuits.}, journal={ADVANCED OPTICAL MATERIALS}, author={Lin, Dayang and Liu, Jinbo and Haroldson, Ross and Moon, Jiyoung and Li, Zhitong and Zakhidov, Anvar and Hu, Wenchuang and Gu, Qing}, year={2022}, month={Oct} }
