Optical frequency comb, a Nobel Prize-winning device, can emit numerous evenly spaced and phase-coherent laser lines simultaneously. Besides metrology, attosecond science, and optical communication, frequency comb has recently become an extremely powerful tool for high-precision spectroscopy.
Electro-optical systems play a critical role in numerous applications, such as remote sensing, space exploration, laser communication, aerial imaging, and other pertinent domains. High-accuracy optical beam stabilization of large-aperture electro-optical systems remains a challenging task, especially under complex imaging environments.
Rapid identification of marine microorganisms is critical in marine ecology, and Raman spectroscopy is a promising means to achieve this. Single cell Raman spectra contain the biochemical profile of a cell, which can be used to identify cell phenotype through classification models.
Full-color flexible micro-LED devices are hot spots in the fields of wearable devices and vehicle displays. In previous studies, only blue and violet flexible micro-LEDs have been fabricated. In order to realize full-color display based on flexible micro-LEDs, it is necessary to study the method of realizing full-color display using color conversion technology.
Solar spectral irradiance (SSI) is a key parameter to study the composition, temperature, and dynamics of the Sun over time. An accurate SSI model leads to a better understanding of solar activity.
Micro-LED display technology is considered to be the next generation display technology. However, its large-scale commercialization still faces the challenge of immature technology and high cost. One of the challenges is how to realize the full color of Micro-LED.
