Vertical cavity laser In VCSEL lasers, the quantum well is between two Bragg reflectors. Could the reflectors be made by etching 1/4-wavelength dimples into the material? That case the material-air interface acts as a diffractive mirror creating a focus for the quantum well. In the middle of the picture is the irradiance distribution in the quantum well and at the top is the yellow metallization circle and the exaggerated surface etching pattern in material. Below is a matching etching pattern and metallized surface mirror. Since lasing would take place from a spatially narrow area, the beam spreads only slightly in the far field.

#mathematics Angles Angle is a measure of rotation of a given ray about its initial point. The original ray is called the initial side and the final position of the ray after rotation is called the terminal side of the angle. The point of rotation is called the vertex. If the direction of rotation is anticlockwise, the angle is said to be positive and if the direction of rotation is clockwise, then the angle is negative. The measure of an angle is the amount of rotation performed to get the terminal side from the initial side. There are several units for measuring angles. The definition of an angle suggests a unit, one complete revolution from the position of the initial side.

Reconstruction of Hydraulic Fractures Using Passive Ultrasonic Travel-Time Tomography 💡The knowledge of hydraulic fracture morphology is significant for the analysis of fracture mechanisms. This paper utilizes passive Ultrasonic Travel-time Tomography (UTT) to characterize the hydraulic fracture. We constructed a velocity model based on X-ray computerized tomography (X-CT) images scanned on a real hydraulically fractured shale column. Then, ray-paths and travel times corresponding to the source-receiver configuration were calculated by curved ray-tracing schemes. Lastly, we performed tomographic inversions using total variation regularization (TVR). 💡The simulation results showed that 3D passive UTT based on TVR is an accurate, efficient, and stable method to reconstruct the velocity structures with fractures, even in the case of sparse ray-coverage or high noise level. Meanwhile, we also verified that the passive UTT is a valid alternative to X-CT in depicting the hydraulic fracturing rock via a proper interpretation method.
