Metamaterial absorbers (MA) based on subwavelength periodic patterns can achieve perfect absorption at any target wavelength by rationally designing their geometric parameters. Due to their ultra-thin thickness and near-field enhancement, MAs are widely used in infrared imaging, thermal...
Researchers Proposed Efficient Inorganic Perovskite Light-Emitting Diodes by Inducing Grain Arran...
Metal halide perovskite material is a new type of photoelectric material with a range of advantages, such as high absorption coefficient, long carrier diffusion length, high mobility, and a tunable band gap. These advantages have made metal halide perovskite the spotlight in fields of s...
Researchers proposed an all-fiber-laser-pumped mid-infrared MgO:PPLN optical parametric oscillator
MgO-doped periodically poled lithium niobate (MgO:PPLN) optical parametric oscillators (OPOs) have the ability to generate high-power mid-infrared (MIR) laser with high efficiency. They have important applications in the fields of atmosphere monitoring, laser spectroscopy, photoelectric...
A zigzag-shaped tapered optical microfibers interferometer was invented operating at the dispersi...
The dispersion turning point (DTP) in microfibers has proven to be an effective exceptional phenomenon for sensitivity improvement. In order to break the adiabaticity condition and excite higher-order modes effectively to satisfy the condition of DTP, the transition segments of tapered ...
Researchers super-resolved remote sensing images without using high-resolution labels
High resolution (HR) remote sensing images play an important role in environment monitoring, military reconnaissance, and urban planning. However, the direct acquisition of numerous HR images requires high-performance imaging equipment, while improving image resolution with super-resolu...
Light People: Professor Byoungho Lee
Major developments were made recently in both VR (virtual reality) and AR (augmented reality) technologies, which became the focus of attention. In recent years, MR (mixed reality) technology has also emerged, and optical components play an irreplaceable role in these technologies.
Researchers proposed design method for reflective optical system with low tilt-error sensitivity
Characterized by large aperture and long focal length, the reflective optical system has the advantages of small number of optical elements and simple optical structure. But the intrinsic aberration and the misalignment derived aberration increase exponentially with the increase of foca...
