Abstract

We suggest and analyze a new type of microscopic laser, which uses a highly dispersive mirror to achieve stable dual-mode lasing. The mirror-dispersion is implemented using electromagnetically induced transparency (EIT) between two coupled nanocavities and allows a beat note frequency that is dynamically tunable. In contrast, a conventional laser resonator of the same length cannot address this frequency range. Thus, the proposed laser has potential applications in photonic microwave generation, terahertz sensing, and all-optical clock recovery [1].

All-optically controlled mode-coupling induced transparency with tunable efficiency in a microsphere resonator

Weichen Yuan, H. Y. Fu

The optical analogs of electromagnetically induced transparency (EIT) have attracted vast attention recently. The generation and manipulation of EIT in microcavities have sparked research in both fundamental physics and photonic applications, including light storage, slow light propagation, and optical communication. In this Letter, the generation and tuning of an all-optically controlled mode-coupling induced transparency (MCIT) are proposed, experimentally demonstrated, and theoretically analyzed. The MCIT effect originated from the intermodal coupling between the plethora of modes generated in our fabricated optical microcavity, and the tuning of the transparency mode utilized the cavity's thermal bistability nature. Furthermore, based on our method, a novel, to the best of our knowledge, controlling of the mode shifting efficiency is also achieved with an increase up to two times and more. The proposed scheme paves a unique, simple, and efficient way to manipulate the induced transparency mode, which can be useful for applications like cavity lasing and thermal sensing.

Laser frequency offset locking using electromagnetically induced transparency

S. C. Bell, D. Heywood, J. D. White +2 more

The authors have used an electromagnetically induced transparency resonance in rubidium as a dispersive reference to lock the relative frequency of two lasers to the atomic ground-state hyperfine splitting. The beat frequency between the two lasers directly generates a microwave signal at 3.036GHz (Rb85) or 6.835GHz (Rb87). High bandwidth (600kHz) feedback was achieved with only low-frequency (10MHz) electronics using the frequency modulation sideband method. The spectral width of the microwave beat frequency was reduced to less than 1kHz. The technique offers a convenient and low-cost method suitable for many topical two-frequency experiments, including coherent population trapping, slow light, lasing without inversion, and Raman sideband cooling.

Dual-mode electromagnetically induced transparency and slow light in a terahertz metamaterial

Kun Zhang, Cheng Wang, Ling Qin +4 more

In this Letter, we construct a metamaterial with dual-mode electromagnetically induced transparency (EIT)-like behavior by introducing "bright atoms," "quasi-dark atoms," and "dark atoms" simultaneously. The dual-mode EIT-like behavior has been demonstrated both experimentally and theoretically in terahertz (THz) regime. At two EIT-like modes, slow light is also observed as two time-delayed wave packets, and the effective group refractive index can reach 10(2). Furthermore, stable dual-mode EIT-like behavior is verified in this metamaterial for a wide range of oblique incident angles. Our work provides a design approach to mimic dual-mode EIT, and such an approach may achieve potential applications on miniaturized and versatile THz devices.

The metamaterial analogue of electromagnetically induced transparency by dual-mode excitation of a symmetric resonator

Jian Shao, Jie Li, Jia-Qi Li +4 more

Electromagnetically induced transparency (EIT) is obtained in a symmetric U-shaped metamaterial, which is attributed to the simultaneously excited dual modes in a single resonator under lateral incidence. A large group index accompanied with a sharp EIT-like transparency window offers potential applications for slowing down light and sensing.
