There was a question from Jerry in a previous post: "A simple question for which I can't find an answer: Why do you have to collimate light spectroscopy? What would happen if you didn't collimate it?" ...

What prompted the MIT team to research and develop a nanoscale "flashlight"? Details on the metasurface that was designed to create the source-beam collimator. How a DNN, CNN, and machine learning ...

Semiconductor lasers are uniquely suited to a variety of applications because they have extremely high efficiency compared to other laser media and can be designed to produce a wide range of ...

Figure 1: Physical system under study. Figure 2: Experimental and theoretical evolution of the beam in the PhC. It is important to note that although the beam width used to excite the PhC is 1.0 μm ...

The investigation of ultrafast electronic and structural dynamics in low-dimensional systems such as nanowires and two-dimensional materials requires femtosecond probes providing high spatial ...

2D-XRD, or two-dimensional X-ray diffraction, is a powerful analytical technique used to study the atomic and molecular structure of crystalline materials at the nanoscale. It provides detailed ...

Towards the end of the 19th century, Abbe and Rayleigh formulated the principles of optical diffraction that limits the resolution of optical instruments in the far-field where the distance between ...
