Abstract

We describe nonlinear and quantum interactions of photons in chip-scale nanostructures and photonic crystals, including slow-light four-wave-mixing, femtosecond solitons, cavity optomechanics, quantum electrodynamics and information processing.

Single photon nonlinear optics on photonic crystal chips

Dirk Englund

A single semiconductor quantum dot that is strongly coupled to a photonic crystal nanocavity yields optical nonlinearities at the single photon level. The promise of quantum information processing is driving developments in several different physical implementations. Photons are attractive as carriers of quantum information be-cause they can travel long distances without losing their infor-mation through interactions with their environment. However, their passive nature can be a problem in applications such as the construction of logic gates, where it is necessary for two or more photons to interact. This interaction requires a nonlinear optical medium. Particularly strong nonlinearities are achieved when photons drive an emitter near its resonance frequency, and this nonlinearity is even greater if the photon is confined near the emitter in an optical cavity.

Tunable dissipative solitons in a parametric oscillator based on atomic four-wave mixing

Sutapa Ghosh, Brielle E. Anderson, Gregory T. Moille +3 more

Temporal dissipative solitons are central to nonlinear photonics, yet conventional platforms such as optical fibers and microresonators provide limited dispersion tunability and weak nonlinearities. Here, we demonstrate a highly tunable soliton platform based on atom–light interactions in a rubidium vapor optical parametric oscillator. A continuous-wave pump drives four-wave mixing in the vapor, generating probe and conjugate fields, one of which is fed back through a fiber loop to form the oscillator. By tuning the pump intensity and detuning, we control the dispersive properties and third-order nonlinearity of the medium, enabling the formation of diverse nonlinear states including bright and dark solitons, soliton crystals, dark–bright soliton pairs, platicons, and breather solitons. Unlike conventional systems, solitons emerge spontaneously without cavity scanning or pulsed excitation. The system isolates gain, dispersion, and nonlinearity within the atomic medium, allowing flexible cavity-length tuning without modifying other operating parameters. We introduce the technique of characterizing the solitonic states through the linewidth of the output intensity power spectrum, which remains independent of cavity length and is limited only by the experimental apparatus, indicating a high degree of phase coherence. This contrasts with conventional mode-locked states, for which the linewidth scales inversely with the square of the cavity length. With pulse durations of ∼100 ns determined by the gain bandwidth of the four-wave mixing, the solitons can be directly detected for rapid and complete characterization. This platform offers a versatile route for exploring nonlinear optical dynamics and developing applications in quantum photonics and communication.

Topologically protecting squeezed light on a photonic chip

Ruo-Jing Ren, Yong‐Heng Lu, Ze-Kun Jiang +7 more

Squeezed light is a critical resource in quantum sensing and information processing. Due to the inherently weak optical nonlinearity and limited interaction volume, considerable pump power is typically needed to obtain efficient interactions to generate squeezed light in bulk crystals. Integrated photonics offers an elegant way to increase the nonlinearity by confining light strictly inside the waveguide. For the construction of large-scale quantum systems performing many-photon operations, it is essential to integrate various functional modules on a chip. However, fabrication imperfections and transmission cross talk may add unwanted diffraction and coupling to other photonic elements, reducing the quality of squeezing. Here, by introducing the topological phase, we experimentally demonstrate the topologically protected nonlinear process of four-wave mixing, enabling the generation of squeezed light on a silica chip. We measure the cross-correlations at different evolution distances for various topological sites and verify the nonclassical features with high fidelity. The squeezing parameters are measured to certify the protection of cavity-free, strongly squeezed states. The demonstration of topological protection for squeezed light on a chip brings new opportunities for quantum integrated photonics, opening novel approaches for the design of advanced multi-photon circuits.

Entangled photons from on-chip slow light

Hiroki Takesue, Nobuyuki Matsuda, Eiichi Kuramochi +1 more

We report the first entanglement generation experiment using an on-chip slow light device. With highly efficient spontaneous four-wave mixing enhanced by the slow light effect in a coupled resonator optical waveguide based on a silicon photonic crystal, we generated 1.5-μm-band high-dimensional time-bin entangled photon pairs. We undertook two-photon interference experiments and observed the coincidence fringes with visibilities >74%. The present result enables us to realize an on-chip entanglement source with a very small footprint, which is an essential function for quantum information processing based on integrated quantum photonics.
