Researchers 'tinkered' with 2D metamaterials and created 'photonic time crystals' that could have revolutionary implications for lasers and transmitters.
Researchers have just released a study that explains how they've managed to design a two-dimensional "photonic time crystal" that, they say, could have significant implications for technologies like transmitters and lasers. While their name is similar to that of so-called ""Time crystals" are particular kinds of crystals whose component atoms exist in a quantum state. This means they behave in ways that seem alien or "strange.
Since it has been challenging to construct and manipulate 3D "photonic time crystals," the team decided to try something new by making the material even thinner . By doing so, the researchers report that their crystals can amplify light at microwave frequencies.
"Photonic crystals" are unique materials that can bend and amplify light in a controlled way. Scientists can create these materials in a lab by adjusting their electromagnetic properties using metamaterials. When light travels through "photonic time crystals," the photons move in a repeating pattern that helps keep them in sync and maintain their coherence. This is similar to how lasers keep quantum bits in a coherent state, which can help prolong their quantum properties.
