Photonic integrated circuits with second-order (χ (2)) nonlinearities are rapidly scaling to remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear …
Realization of a room-temperature ultrafast photon-number-resolving quantum nondemolition (QND) measurement would have significant implications for photonic …
Quantum field theory suggests that electromagnetic fields naturally fluctuate, and these fluctuations can be harnessed as a source of perfect randomness. Many potential …
This article reviews recent progress in quasi-phasematched $\chi^{(2)} $ nonlinear nanophotonics, with a particular focus on dispersion-engineered nonlinear interactions …
High-gain optical parametric amplification is an important nonlinear process used both as a source of coherent infrared light and as a source of nonclassical light. In this work, we …
Engineered non-Hermitian systems featuring exceptional points (EPs) can lead to a host of extraordinary phenomena in diverse fields ranging from photonics, acoustics, opto …
We study the emergence of non-Gaussian quantum features in pulsed squeezed light generation with a mesoscopic number (ie, dozens to hundreds) of pump photons. Due to the …
The loss of gauge invariance in models of light-matter interaction which arises from material and photonic space truncation can pose significant challenges to conventional quantum …
Photonics offers unique capabilities for quantum information processing (QIP) such as room- temperature operation, the scalability of nanophotonics, and access to ultrabroad …
