In an innovative study, a multidisciplinary team of researchers has successfully altered the trajectory of light in a manner akin to the influence of gravity. The research, recently published in the journal Physical Review A, presents groundbreaking applications in the areas of optics, materials science, and notably, 6G communications technology.

Albert Einstein's theory of relativity has furnished the scientific community with a foundational understanding that gravitational fields can influence the course of electromagnetic waves, encompassing light and terahertz electromagnetic waves. Recently, theoretical studies have posited the potential for "pseudogravity"-artificially simulated gravitational effects-through crystal deformation at specific frequencies.

Professor Kyoko Kitamura of Tohoku University's Graduate School of Engineering explained their research focus, "We set out to explore whether lattice distortion in photonic crystals can produce pseudogravity effects."

Photonic crystals function as essential mediums for manipulating light. These crystals are organized by periodically placing two or more disparate materials with unique light interaction properties into a repetitive pattern. The ability to induce pseudogravity effects via adiabatic changes has been previously documented within these photonic structures.

For their study, Kitamura and her colleagues experimented with photonic crystals by applying lattice distortion. Essentially, they introduced subtle alterations to the regular arrangement of components within the crystals. This distortion interfered with the photonic crystal's inherent grid-like structure, thus modifying its photonic band structure. The outcome was a curving trajectory of light within the medium-akin to light rays veering near a massive astronomical entity, such as a black hole.

The researchers utilized a silicon-based distorted photonic crystal with a primal lattice constant measuring 200 micrometers and employed terahertz waves in their experiments. The result was a successful deflection of these waves, aligning with the intended theoretical effects.

Associate Professor Masayuki Fujita from Osaka University elaborated on the wider applications of this work. "Much like gravity bends the trajectory of objects, we came up with a means to bend light within certain materials," he said. "Such in-plane beam steering within the terahertz range could be harnessed in 6G communication. Academically, the findings show that photonic crystals could harness gravitational effects, opening new pathways within the field of graviton physics."

The study has the potential to be a cornerstone in the evolving landscape of optics and materials science. Moreover, the specific applications of this research in the realm of 6G communications technology offer a tangible avenue for further exploration and development. Thus, the work not only confirms the theoretical potential of pseudogravity effects in photonic crystals but also indicates practical uses that could shape future technological advancements.
