  text: We introduce a new classification of multimode states with a fixed number
    of photons. This classification is based on the factorizability of homogeneous
    multivariate polynomials and is invariant under unitary transformations. The classes
    physically correspond to field excitations in terms of single and multiple photons,
    each of which being in an arbitrary irreducible superposition of quantized modes.
    We further show how the transitions between classes are rendered possible by photon
    addition, photon subtraction, and photon-projection nonlinearities. We explicitly
    put forward a design for a multilayer interferometer in which the states for different
    classes can be generated with state-of-the-art experimental techniques. Limitations
    of the proposed designs are analyzed using the introduced classification, providing
    a benchmark for the robustness of certain states and classes.

  text: <jats:p>Bell measurements, entailing the projection onto one of the Bell states,
    play a key role in quantum information and communication, where the outcome of
    a variety of protocols crucially depends on the success probability of such measurements.
    Although in the case of qubit systems, Bell measurements can be implemented using
    only linear optical components, the same result is no longer true for qudits,
    where at least the use of ancillary photons is required. In order to circumvent
    this limitation, one possibility is to introduce nonlinear effects. In this work,
    we adopt the latter approach and propose a scalable Bell measurement scheme for
    high-dimensional states, exploiting multiple squeezer devices applied to a linear
    optical circuit for discriminating the different Bell states. Our approach does
    not require ancillary photons, is not limited by the dimension of the quantum
    states, and is experimentally scalable, thus paving the way toward the realization
    of an effective high-dimensional Bell measurement.</jats:p>

  text: <jats:p>Frequency-filtered photon correlations have been proven to be extremely
    useful in grasping how the detection process alters photon statistics. Harnessing
    the spectral correlations also permits refinement of the emission and unraveling
    of previously hidden strong correlations in a plethora of quantum-optical systems
    under continuous-wave excitation. In this work, we investigate such correlations
    for time-dependent excitation and develop a methodology to compute efficiently
    time-integrated correlations, which are at the heart of the photon-counting theory,
    and subsequently apply it to analyze the photon emission of pulsed systems. By
    combining this formalism with the —which facilitates frequency-resolved correlations—we
    demonstrate how spectral filtering enhances single-photon purity and suppresses
    multiphoton noise in time-bin-encoded quantum states. Specifically, filtering
    the central spectral peak of a dynamically driven two-level system boosts temporal
    coherence and improves the fidelity of time-bin entanglement preparation, even
    under conditions favoring multiphoton emission. These results establish spectral
    filtering as a critical tool for tailoring photon statistics in pulsed quantum
    light sources.</jats:p>

  text: <jats:p>Boson sampling is a key candidate for demonstrating quantum advantage
    and has already yielded significant advances in quantum simulation, machine learning,
    and graph theory. In this work, a unification and extension of distinct forms
    of boson sampling is developed. The devised protocol merges discrete-variable
    scattershot boson sampling with continuous-variable Gaussian boson sampling. Therefore,
    it is rendered possible to harness the complexity of more interesting states,
    such as squeezed photons, in advanced sampling protocols. A generating function
    formalism is developed for the joint description of multiphoton and multimode
    light undergoing Gaussian transformations. The resulting analytical tools enable
    one to explore interfaces of different photonic quantum-information-processing
    platforms. A numerical simulation of unified sampling is carried out, benchmarking
    its performance, complexity, and scalability. Entanglement is characterized to
    exemplify the generation of quantum correlations from the nonlinear interactions
    of a unified sampler.</jats:p>

  text: '<jats:p>Entangled two-mode Gaussian states constitute an important building
    block for continuous variable quantum computing and communication protocols. In
    this work, we theoretically study two-mode bipartite states, which are extracted
    from multimode light generated via type-II parametric downconversion (PDC) in
    lossy waveguides. For these states, we demonstrate that the squeezing quantifies
    entanglement and we construct a measurement basis, which results in the maximal
    bipartite entanglement. We illustrate our findings by numerically solving the
    spatial master equation for PDC in a Markovian environment. The optimal measurement
    modes are compared with two widely used broadband bases: the Mercer–Wolf basis
    (the first-order coherence basis) and the Williamson–Euler basis.</jats:p>'

  text: Samples of dielectric optical waveguides of rib or strip type in thin-film
    lithium niobate (TFLN) technology are characterized with respect to their optical
    loss using the Fabry-Pérot method. Attributing the losses mainly to sidewall roughness,
    we employ a simple perturbational procedure, based on rigorously computed mode
    profiles of idealized channels, to estimate the attenuation for waveguides with
    different cross sections. A single fit parameter suffices for an adequate modelling
    of the effect of the waveguide geometry on the loss levels.

  text: Lateral leakage of TM modes in dielectric optical waveguides of rib/ridge
    or strip-loaded types can be fully suppressed, if the waveguide core is formed
    not through a strip that protrudes at one side (up) from the remaining lateral
    guiding slab, but through parallel strips on both sides (up and down), such that
    the resulting cross section becomes vertically symmetric. The fairly general arguments
    underlying the leakage suppression apply to TM modes of all orders simultaneously,
    and are independent of wavelength. These plus-shaped waveguides support strictly
    guided, non-leaky TM modes for, in principle, arbitrarily shallow etching.

  text: Phased arrays are vital in communication systems and have received significant
    interest in the field of optoelectronics and photonics, enabling a wide range
    of applications such as LiDAR, holography, wireless communication, etc. In this
    work, we present a blazed grating antenna that is optimized to have upward radiation
    efficiency as high as 80% with a compact footprint of 3.5 μm × 2 μm at an operational
    wavelength of 1.55 μm. Our numerical investigations demonstrate that this antenna
    in a 64 × 64 phased array configuration is capable of producing desired far-field
    radiation patterns. Additionally, our antenna possesses a low side lobe level
    of -9.7 dB and a negligible reflection efficiency of under 1%, making it an attractive
    candidate for integrated optical phased arrays.

  text: 'Dielectric slab waveguides made of thin-film-lithium-niobate (TFLN) media
    are consid-ered, for operation in the linear regime. We outline and implement
    a largely analytic procedure forrigorous modal analysis of three-layer slabs with
    birefringent, anisotropic core. For Z-cut wave-guides, the slab eigenmode problem
    separates into uncoupled sets of scalar equations for TE andTM modes. Slabs in
    X-cut configuration support mostly mildly hybrid eigenmodes, with clear pre-dominant
    TE or TM polarization, and with effective indices that depend on the propagation
    directionof the modes, relative to the crystal axes. Strong hybridization can
    be observed for near degeneratemodes in singular configurations without vertical
    symmetry, or in symmetric slabs where two nearlydegenerate modes are of the same
    symmetry class. Dispersion curves for slab thickness and propa-gation angle are
    discussed, for slabs with oxide and air cover. '
