Iron Triangle releases fiber Bragg gratings and arrays based on multi-core fibers

In today's rapidly developing technological era, structured light laser technology has become an important tool in the fields of 3D measurement and image capture. The core of this technology lies in a magical device called Diffractive Optical Elements (DOE), which can precisely control and shape laser beams, creating various complex light patterns. But what exactly is DOE? How does it work? Let Ho...

The time/frequency unit is the most accurate among the seven basic units, so many measurement studies that pursue ultra-high accuracy and sensitivity will be transformed into frequency measurements to achieve higher measurement accuracy and sensitivity. For example, by measuring the relative changes in the ratio of different atomic transition frequencies, ultralight dark matter can be detected or ...

Background IntroductionTwo dimensional materials have attracted widespread attention due to their atomic level thickness and unique properties, such as high binding energy, tunable bandgap, and new electronic degrees of freedom (valley electronics). They have many application prospects in fields such as microelectronics, nanophotonics, and nanoenergy. Various two-dimensional materials have their o...

LiDAR sensors are crucial for implementing modern technologies such as autonomous driving, AR/VR, and advanced driving assistance systems. For example, more accurate shape detection in AR/VR devices and smartphones depends on the improved range resolution of medium and short range LiDAR. This requires a single photon detector with improved timing jitter performance.LiDAR calculates the distance an...

Recently, a research team from the Aerospace Laser Technology and Systems Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a new holographic imaging technology using frequency domain direct sampling. The relevant results were published in Optics Letters under the title of "Fourier inspired single pixel holography".Digital holography is a tech...
