MIT engineers recently designed a tunable “metalens” that can zero in on objects at multiple depths. The lens, constructed from a transparent “phase-changing” material capable of rearranging its atomic structure after heating, is capable of transforming how its material interacts with light. The invention is a breakthrough in the field of photonics. Traditionally, changing the […]
In 2020, photonics researchers used the finite element method (FEM) to make a number of exciting discoveries in the field of optics. As discussed in a previous post, FEM is a numerical solution that breaks down a much larger, complex problem into a series of smaller ones (“finite elements”) in order to make the overall […]
The majority of medical, scientific, and industrial applications utilize high-power diode-lasers (HPDLs). Due to the common use of HPDLs, it’s more important than ever to prevent optical and physical malfunctions in high-power laser packages. However, as laser technology has become more advanced, HPDL output power has gotten larger, and with it, the waste-heat energy density […]
Optical lenses are vital components to the manufacturing and labeling of goods. For example, optical lenses are found in electronic devices like smartphones and laptops. They’re also used to make logos and graphics on hardware as well as other kinds of markings commonly found on commercial products and food packaging. These markings are created by […]
Exciting developments are happening in the fields optics and photonics. Some of these innovations are being made with the help of the finite element method (FEM). As discussed in a previous post, FEM is a numerical solution for a complex problem, which is used to create simulations. These simulations help researchers understand how all the […]

The finite element method (FEM) can be used to create a range of photonics applications that can be used in astronomy, telecommunications, sensing, chemistry, biomedical R&D, and more. How […]
The finite element method (FEM) and finite element analysis (FEA) work together to give engineers insight into the structural behavior of particular designs, so they can locate weak points and improve them. FEM: Developed by engineers in the mid-1950s, FEM provides a numerical solution for a complex problem, which allows for some level of error. […]
Widely popular among the engineering community, the finite element method (FEM) is a numerical technique used to perform finite element analysis of any given physical phenomenon. It has simple, compact, and results-oriented features that are appealing to engineers. Here are six advantages to this technique: Modeling. FEM allows for easier modeling of complex geometrical and […]
The finite element method (FEM) was independently developed by engineers, beginning in the mid-1950s. It approaches structural mechanics problems. The method started with promise in the modeling of several mechanical applications in the aerospace and civil engineering industries. But What Exactly Is It? WiseGeek describes FEM as: “The finite element method is a tool for […]
