A silicon photonic chip space coupling system is studied, which simplifies the coupling mode of integrated photonic chip with optical fiber array, Through the spatial optical system, the light in the band near 1550 nm is verticall

The terahertz photoconductive antenna driven by femtosecond laser is a common terahertz source in terahertz time-domain spectroscopic system. Because of its omni-directional radiation mode, the main lobe of photoconductive antenna

With the rapid expansion of laser application fields, the laser with ultra-high peak power and ultra-narrow pulse width has gradually become one of the important research directions of the laser fields in the future. These laser w

In this paper, we designed a photon-number-resolving single-photon detector based on an avalanche photodiode, which used a short-pulse gated signal combining with a capacitive balanced noise suppression scheme to achieve a single-

Traditional surgical navigation systems require operators to switch their eyes between the display screen and the lesion area. In order to solve this problem, augmented reality surgical navigation has been applied. This paper desi

Raman spectroscopy can identify the spectral characteristic peaks of plastic products, but the operation process is complicated and the accuracy needs to be improved. Therefore, a classification algorithm for plastic products base

Due to high conductivity and large specific surface area, 2D titanium carbide (Ti3C2Tx) can be used as an electrode material for supercapacitors with high energy density. However, the deactivation of Ti3C2Tx through irreversible o
