Web1 de set. de 2012 · An electrically pumped III-V - silicon heterogeneous VCSEL is demonstrated using a high-contrast grating (HCG) reflector on silicon. CW output … Web30 de jan. de 2024 · A high-contrast grating (HCG) is a label-free optical biosensor with a spectral linewidth of approximately 500 pm and is sensitive to ligand-induced changes in surface properties . The small footprint and high efficiency of an HCG structure can be suitable for wavelength conversion in chip-scale integrated optics. WebThe improvements due to small incision lenticule extraction (SMILE) in vision, e.g., in spherical equivalent (SE) and visual acuity (VA), has been widely recognized. However, the contrast sensitivity (CS) change after SMILE was not certain. Here, we investigated the effect of SMILE on CS before, 1 day after and 7 days after surgery and then clarified the … own way翻译
