“…This contributes, along with spherical aberration and mirror surface defects, to the finite bandwidth (small spread) of modes seen in Fig. 2(a) for δL ¼ 0 μm [9,27]. The mode degeneracy is maximal when L ¼ R, as shown in Fig.…”

“…These interactions may be sufficiently strong to create novel quantum phases of matter [4]. Indeed, single-and few-mode cavity QED in the optical domain have already provided demonstrations of supersolidity [5,6] and exotic Mott physics [7,8], in addition to supermode-density-wave-polariton condensation [9]. Moreover, the driven-dissipative, openquantum-system nature of cavity QED can change the character of quantum phase transitions, providing a new window into quantum nonequilibrium physics [10,11].…”

“…With this transversely pumped, far-detuned configuration, condensation of supermode-density-wave polaritons was subsequently demonstrated in Ref. [9] in the regime of a few degenerate modes. Two crossed single-mode cavities with a BEC coupled to both was shown to exhibit a Uð1Þ symmetry in the superradiant, self-organization phase as well as a Higgs mode [5,6].…”

Optical cavity QED provides a platform with which to explore quantum many-body physics in drivendissipative systems. Single-mode cavities provide strong, infinite-range photon-mediated interactions among intracavity atoms. However, these global all-to-all couplings are limiting from the perspective of exploring quantum many-body physics beyond the mean-field approximation. The present work demonstrates that local couplings can be created using multimode cavity QED. This is established through measurements of the threshold of a superradiant, self-organization phase transition versus atomic position. Specifically, we experimentally show that the interference of near-degenerate cavity modes leads to both a strong and tunable-range interaction between Bose-Einstein condensates (BECs) trapped within the cavity. We exploit the symmetry of a confocal cavity to measure the interaction between real BECs and their virtual images without unwanted contributions arising from the merger of real BECs. Atom-atom coupling may be tuned from short range to long range. This capability paves the way toward future explorations of exotic, strongly correlated systems such as quantum liquid crystals and driven-dissipative spin glasses.

“…Since the LG modes form a complete basis, the constructed cavity can be used to supporting other kinds of beam structures. As a completely degenerate cavity in principle, it can also be used to generate lasers and entangled photon sources with high dimensional LG modes [19][20][21][22] and other related fields [23][24][25]. Our work opens the way to manipulate the synthetic degrees of freedom for OAM states.…”

Degenerate cavity supporting more than 31 Laguerre–Gaussian modes

et al. 2017

Photons propagating in Laguerre-Gaussian modes have characteristic orbital angular momenta, which are fundamental optical degrees of freedom. The orbital angular momentum of light has potential application in high capacity optical communication and even in quantum information processing. In this work, we experimentally construct a ring cavity with 4 lenses and 4 mirrors that is completely degenerate for LaguerreGaussian modes. By measuring the transmitted peaks and patterns of different modes, the ring cavity is shown to supporting more than 31 Laguerre-Gaussian modes. The constructed degenerate cavity opens a new way for using the unlimited resource of available angular momentum states simultaneously. The Laguerre-Gaussian (LG) modes are solutions for beam profiles with circularly symmetric. They are written in cylindrical coordinates using Laguerre polynomials and shown to obtained well-defined orbital angular momentum (OAM) [1]. The phase fronts of light beams in OAM eigenstates rotate, clockwise for positive OAM values, anti-clockwise for negative values, which could result in some unique features. The synthetic dimension with the values of OAM defined as the dimensional basis is recognized as a unique asset in many studies, including high-capacity optical communication [2,3], versatile optical tweezers [4], quantum information and quantum foundation [5][6][7]. It has been recently demonstrated quantum entanglement involving angular momenta as high as hundreds [6,8]. The manipulation and measurement of OAM states can be reached with high precision [5,[9][10][11], which leads to new applications of OAM states, such as detecting of a spinning object and lateral motion [12,13].Although, in principle, there are infinite synthetic degrees of freedom for OAM states, how to construct some functional devices by manipulating them in the synthetic dimension become a subject to be developed. Recently, a new kind of photonics simulator based on energy-degenerated optical cavities has been theoretically presented, which can support a large number of OAM modes [14]. By taking advantage of such kind of optical cavity, one can simulate photonics topological matters, as well as construct all-optical devices by manipulating in photonic synthetic dimension [15,16]. All such potentially novel applications are ascribed to set up a kind of degenerate optical cavity, which can support plenty of energy-degenerated OAM modes.Here, we present an experimental framework using numbers of OAM states in an optical cavity simultaneously, which is referred to a degenerate cavity. Different from previous works with OAM in cavities [17,18], we precisely measure the transmitted peaks and beam profles of different modes in the cavity, which is shown to supporting more than 31 LG modes. Moreover, the constructed cavity is in principle completely degenerate, which can be used to generate lasers and entangled photon sources with high dimensional LG modes [19][20][21][22] and other related fields [23][24][25].The theoretical framework of a degenera...

Mid-infrared (MIR) semiconductor laser sources are essential for applications in gas detection, infrared imaging, and high-speed free space optical communications. At present, the dynamic wavelength tunability of MIR lasers based on lead salt, antimonide, and quantum cascade lasers is limited and their compact size as well as heterogeneous integration are still challenging. Two-dimensional (2D) materials, used as optical gain materials, have the flexible tunability and compatible van der Waals integrations-providing many new possibilities for constructing MIR laser sources of large tunability and high integration. Here, wide-wavelength tunable MIR vertical cavity surface emitting lasers (VCSELs) integrated on silicon substrates are realized based on 2D black arsenic phosphorus (b-As x P 1−x ). The emission wavelength of the optically pumped laser device is demonstrated to be tuned from 3.42 to 4.65 μm at room temperature, which could be controlled by adjusting the alloy composition and thickness of the gain media b-As x P 1−x . The tunable MIR VCSEL device would pave the way for further exploration of 2D materials-based IR lasers working as on-chip light sources.
