Non-equilibrium and collective behaviors such as phase transitions in optical systems can lead to interesting applications in photonics. Here the authors demonstrate spectral phase transition in a ubiquitous nonlinear driven-dissipative system, the o

Miniaturization of optical components could give way to dense photonic-integrated circuits. Here, the authors demonstrate the control of evanescent waves using all-dielectric metamaterials and show that they can reduce cross-talk and bending loss, wh

Total internal reflection (TIR) is a ubiquitous phenomenon used in photonic devices ranging from waveguides and resonators to lasers and optical sensors. Controlling this phenomenon and light confinement are keys to the future integration of nanoelec

We demonstrate quadratic soliton formation in a synchronously pumped degenerate optical parametric oscillator displaying significant pulse compression leading to the formation of femtosecond pulses at half-harmonic from picosecond pump pulses.

Current crowding at bends of superconducting nanowire single-photon detector (SNSPD) is one of the main factors limiting the performance of meander-style detectors with large filling factors. In this paper, we propose a new concept to reduce the infl

Strong amplification in integrated photonics is one of the most desired optical functionalities for computing, communications, sensing, and quantum information processing. Semiconductor gain and cubic nonlinearities, such as four-wave mixing and stim

We demonstrate phase-sensitive amplification and confirm aga in exceeding 100 dB/cm on a dispersion-engineered thin-film lithium niobate waveguide, using less than 20 pJ of pump energy, and exhibiting a gain bandwidth larger than 600 nm around 2.09
