Mid-infrared giant optical chirality induced by multipole degeneracy in a diamond metasurface.
Optical chirality is a fundamental property of light that plays a crucial role in chiroptical spectroscopy, analytical chemistry, spin photonics, and astrobiology. However, giant optical chirality at the wavelength beyond 15 μm remains untapped, which hinders its various applications, such as ultrasensitive vibrational circular dichroism, in the mid-infrared region. Here we propose and theoretically present giant optical chirality with a, to our knowledge, record-high value of ∼330 at the wavelength beyond 15 μm in a diamond metasurface. This is enabled by tailoring the multipole degeneracy and leveraging the low optical loss of the diamond metasurface. This work provides a new method for boosting the optical chirality at the wavelength beyond 15 μm.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
