Summary
We created a network model for coupled laser arrays, simplifying analysis of mixed coupling schemes. This model allows precise calculation of array modes and near-field patterns for advanced laser designs.
Area of Science:
- Optics and Photonics
- Semiconductor Lasers
- Array Physics
Background:
- Phase-locked laser arrays are crucial for high-power coherent emission.
- Modeling complex coupling schemes in two-dimensional arrays remains challenging.
- Existing models often struggle with mixed lateral and longitudinal coupling.
Purpose of the Study:
- To develop a versatile network model for analyzing two-dimensional phase-locked laser arrays.
- To enable the study of arrays with mixed coupling configurations (lateral and longitudinal).
- To provide a framework for calculating array modes and near-field emission patterns.
Main Methods:
- A network model was developed to represent coupled laser arrays.
- The model decomposes array modes based on lateral (evanescent) and longitudinal (injection) coupling.
- Eigenvalue analysis of matrices representing each coupling type was employed.
- A 3x3 array with specific Bragg reflector coupling was analyzed as a case study.
Main Results:
- The modes of two-dimensional arrays with mixed coupling can be expressed using separate lateral and longitudinal coupling matrices.
- The model successfully predicts modes and grating-coupled near-field patterns.
- Explicit calculations were performed for a 3x3 array with surface-emitting Bragg reflectors.
Conclusions:
- The developed network model offers a powerful and flexible approach for analyzing complex laser arrays.
- This method simplifies the understanding and design of two-dimensional laser arrays with mixed coupling.
- The findings are applicable to the design of advanced laser sources, including those using Bragg reflectors.

01:29Lines in Space
In three-dimensional analytic geometry, a line can be fully described using vector equations when both a point on the line and its direction are known. This approach has practical applications in fields such as engineering and surveying, where precise spatial modeling is essential. For instance, a laser beam from a surveying instrument directed across a construction site can be modeled mathematically as a line using vectors.Let the laser beam originate from a known point P₀, represented by the...

The Bewley lattice diagram, developed by L. V. Bewley, effectively organizes the reflections occurring during transmission-line transients. It visually represents how voltage waves propagate and reflect within a transmission line, making it easier to understand the complex interactions that occur.
01:12Two-Dimensional (2D) NMR: Overview
The 1D NMR spectrum of large and complex molecules like natural products has complicated splitting patterns and overlapping signals, which can be easily interpreted using 2-dimensional (2D) NMR. Unlike 1D NMR, 2D NMR has two frequency axes that provide the coupling information between the nucleus A and nucleus B in a molecule. The process from which 2D spectra are obtained has four steps.
The first step is the preparation period, during which nucleus A is excited with a radiofrequency pulse.

01:27Gauss's Law: Planar Symmetry
A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...
