Article Abstract
A three-dimensional notched-elliptical microdisk with a wavelength-size notch on the boundary is proposed as a multi-wavelength and unidirectional emission lasing source. The device contains multiple properly designed two-dimensional whispering gallery mode-based polymer notched microdisks with different dimensions for use as a multi-wavelength source. It can have a relatively high optical quality factor of 4000, unidirectional emission with low far-field divergence ∼4°, and the efficiency of emission is as high as 84.2%. The effect of the notch size on the far-field divergence is analyzed, and the multi-wavelength lasing performance is characterized, demonstrating that the resonator is robust and reliable. This work paves a unique but generic way for the design of compact multi-wavelength microlasers.

The global community faces a critical challenge as rising CO emissions threaten both environmental sustainability and human well-being. The swift addressing of these issues is crucial to preserving and enhancing environmental integrity. Therefore, c from 1990 to 2022, advanced statistical methods, including multiple diagnostic tests, Panel-Corrected Standard Errors (PCSE), and Feasible Generalized Least Squares (FGLS), were employed.

We find that both the asymmetry of emission intensity and the propagation phases play crucial roles in determining radiation behavior. Under suitable parameters, we show that the multiple emitters exhibit tunable radiance in the two-emitter case, such as one emitter exhibits superradiance while the other exhibits subradiance.

The two-mode dynamics of the counter-propagating modes - clockwise (CW) and counterclockwise (CCW) and their selection have gained attention in the mid-infrared; however, the underlying switching mechanism has been largely unexplored. Previously, we experimentally demonstrated robust and deterministic mode selection in a ring quantum cascade laser (QCL) with an active outcoupling waveguide.

Shallow depth, near-level coal seams in the mining process mining fissures directly to the surface, by the atmospheric pressure, negative pressure ventilation and repeated mining and other factors, resulting in serious surface air leakage. Taking the 45,206 mining face in Sandaogou Coal Mine as the research object, this study aims to understand the migration patterns and influencing factors of flow fields in shallow buried goaf. The existence of air leakage channels was verified through SF gas release experiments conducted at both the surface and working face.
