Optomechanically tuned electromagnetically induced transparency-like effect in coupled optical microcavities

Abstract

We experimentally demonstrate the electromagnetically induced transparency (EIT)-like effect using a double-wheel microcavity coupled with a silica microtoroid cavity. To match the resonant modes of the two microcavities, we shift the resonant wavelength of the double-wheel microcavity by 1.5 nm via the optical gradient force. The EIT-like transmission spectrum is precisely controlled by changing the distance and the frequency detuning between the two coupled microcavities.

We experimentally demonstrate an all-optical analog to electromagnetically induced transparency (EIT) on chip using coupled high-Q silica microtoroid cavities with Q-factors above 10(6). The transmission spectrum of the all-optical analog to EIT is precisely controlled by tuning the distance between the two microtoroids, as well as the detunings of the resonance frequencies of the two cavities.

Electromagnetically induced transparency in optical microcavities

Yong‐Chun Liu, Bei‐Bei Li, Yun‐Feng Xiao

Abstract Electromagnetically induced transparency (EIT) is a quantum interference effect arising from different transition pathways of optical fields. Within the transparency window, both absorption and dispersion properties strongly change, which results in extensive applications such as slow light and optical storage. Due to the ultrahigh quality factors, massive production on a chip and convenient all‐optical control, optical microcavities provide an ideal platform for realizing EIT. Here we review the principle and recent development of EIT in optical microcavities. We focus on the following three situations. First, for a coupled‐cavity system, all‐optical EIT appears when the optical modes in different cavities couple to each other. Second, in a single microcavity, all‐optical EIT is created when interference happens between two optical modes. Moreover, the mechanical oscillation of the microcavity leads to optomechanically induced transparency. Then the applications of EIT effect in microcavity systems are discussed, including light delay and storage, sensing, and field enhancement. A summary is then given in the final part of the paper.

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.

We study the coupling between a fiber-taper and two whispering-gallery modes simultaneously excited in a single PDMS-coated silica microtoroid theoretically and experimentally. The transmission spectrum of the fiber coupled two-mode resonator shows a sharp electromagnetically-induced-transparency-like window.

Analog of electromagnetically induced transparency in coupled one-dimensional photonic crystal cavities

Feng Tian, Guangya Zhou, Fook Siong Chau +2 more

In this paper, the analog to electromagnetically induced transparency (EIT) in the double-coupled one-dimensional photonic crystal cavities are proposed and experimentally observed. This EIT-like effect is due to the interference of two resonance modes and the leaky propagation mode. A nanoelectromechanical systems (NEMS) comb drive is used to align the two resonant wavelengths up, which is first used in the studies of the EIT-like effect. The fabrication of the device bases on the standard semiconductor process. Finally, the evolution of the EIT-like transmission spectrum with the applied voltages is shown in the last part of this paper.

Electromagnetically induced transparency with a single optomechanical microring resonator

Linhao Ren, Hao Wen, Lei Shi +1 more

An all-optical realization scheme of electromagnetically induced transparency (EIT) in a single silicon optomechanical microring resonator is proposed and demonstrated. Due to the strong mechanical Kerr effect and well-designed microring resonator, two modes with a resonant frequency separation of 292 GHz (2.35 nm) can be tuned into resonance when the control power is about 4.3 µW, and the EIT spectrum is achieved. Our work provides a constructive solution for realizing EIT in a single microcavity with a low mode density. Furthermore, this device is fully integrated on-chip and compatible with current complementary metal-oxide semiconductor (CMOS) processing and has great potential in applications such as light storage, optical sensing, and quantum optics.
