Magnetic splitting of electromagnetically induced transparency and absorption spectra in a standing-wave coupled lambda-type system

Bakht Hussain, Khan Sadiq Nawaz, Muhammad Ilyas +2 more

Abstract We study the splitting of traveling wave and standing wave coupled Electromagnetically Induced Transparency (EIT) and Electromagnetically Induced enhanced Absorption (EIA) lines in the presence of a uniform magnetic field in an Electromagnetically Induced Grating (EIG). We realize a Λ-type system in a room-temperature Doppler-broadened buffer-gas-free, unshielded vapor cell of pure 133Cs atoms. Different orientations of the magnetic field are studied while the polarizations of the coupling and probe laser beams are arranged in the lin⊥lin configuration. The effects of the different field directions on the EIT and the EIG-induced EIA are explained in light of the existing theory. The magnetically induced high-contrast features in the EIG scheme are also discussed in comparison to the low-contrast EIT features observed for the same strengths of magnetic field.

From electromagnetically induced transparency to absorption in planar optical metamaterials

Bo Na, Jinhui Shi, Chunying Guan +1 more

We theoretically investigate the classical analog of electromagnetically induced transparency (EIT) and electromagnetically induced absorption (EIA) in a planar metamaterial at optical frequency, which originates from destructive and constructive interference between dark and radiative elements.The metamaterial consists of two coupled resonators with different geometries.An EIT-like transparent window with low absorption is observed and found to be strongly affected by resonant states of the resonators.The transition between the EIT and EIA is achieved by changing the split width and coupling distance.The absorption is enhanced up to 2.5 times compared with the dipolar case.The excitation of the dark mode is very important for EIT-and EIA-like responses of the proposed metamaterial.The EIT and EIA phenomena offer a potential method for manipulating electromagnetic response in metamaterial-based devices.

Enhancement of electromagnetically induced transparency in metamaterials using long range coupling mediated by a hyperbolic material

Zhiwei Guo, Haitao Jiang, Yunhui Li +2 more

Near-field coupling is a fundamental physical effect, which plays an important role in the establishment of classical analog of electromagnetically induced transparency (EIT). However, in a normal environment the coupling length between the bright and dark artificial atoms is very short and far less than one wavelength, owing to the exponentially decaying property of near fields. In this work, we report the realization of a long range EIT, by using a hyperbolic metamaterial (HMM) which can convert the near fields into high-k propagating waves to overcome the problem of weak coupling at long distance. Both simulation and experiment show that the coupling length can be enhanced by nearly two orders of magnitude with the aid of a HMM. This long range EIT might be very useful in a variety of applications including sensors, detectors, switch, long-range energy transfer, etc.
