Summary: Broadband optical cavity spectroscopy has been applied for trace gas detection, but recently it has been used for measuring extinction coefficients of aerosols. In this study, an Incoherent Broadband Cavity Enhanced Extinction spectrometer was introduced to measure broadband extinction coefficients of ambient aerosols. The spectral dependent single scattering albedo derived from the measured coefficients showed good agreement with monitoring results from a co-located instrument. The IBBCEES is a simple, sensitive, and accurate tool for measuring light extinction coefficients of atmospheric aerosols.

Summary: Solar energy has been widely used as a renewable and clean energy source, but the dilemma of choosing between higher absorption but narrowband or broadband but lower absorption when designing solar irradiation absorbers has greatly limited the development of the solar energy industry. A gradient cavity-thin-film metasurface (GCM) made up of alternating multiple layers of titanium and silicon dioxide exhibits ultra-broadband strong absorption in the dominating portion of the solar irradiation spectrum. This impressive near-unity absorption is attributed to multiple light-matter interactions and provides great potential for practical applications in solar thermal energy harvesting and photothermal conversion.

Summary: An optomechanical scheme is presented to achieve light-controlled logic functions by combining an electromagnetic resonator with a strongly nonlinear nanomechanical oscillator. The nonlinear mechanical oscillations, controlled by external drives, are sensitive to incident light due to enhanced light-matter interactions. Reconfigurable logic functions (NOT, XOR, OR, AND) can be realized by adjusting the initial mechanical configurations to obtain various responses to input optical signals.

Summary: Solitary-like surface waves originating from falling liquid films on an inclined plane under low-frequency vibration have unique properties and are of interest in theoretical and experimental research. We investigated the dynamics of these waves and found that the vibration decreased their average and peak amplitudes, but had little effect on their propagation speed. This makes them suitable for practical applications where pulses carrying information need to be immune to external vibrations.

Summary: Modern sensing and imaging applications require accurate measurements of light wave properties such as intensity, wavelength, directionality, and polarization. This study demonstrates the use of engineered optical resonances in nanostructures to achieve selective detection of circularly polarized light. By patterning a thin silicon layer into a dislocated nanowire-array, it is possible to detect circularly polarized light with high efficiency. The presence of periodic dislocations enables selective excitation of nonlocal, guided-mode resonances for one handedness of light.

Summary: In this study, the emergence of complex pulsing dynamics, including periodic, quasiperiodic, and irregular pulsing regimes, in an excitable microlaser subject to delayed optical feedback is investigated. A mathematical model, written as a system of delay differential equations, is used to perform an in-depth bifurcation analysis. Resonance tongues are found to play a key role in the emergence of complex dynamics.

Summary: The emission dynamics of a multimode broadband interband semiconductor laser have been examined through experimentation and theory. The study reveals the presence of a modulational instability in the nonlinear dynamics of a III-V semiconductor quantum well surface-emitting laser, observed in the anomalous dispersion regime. An additional unstable region arises in the normal dispersion regime due to carrier dynamics, which is not found in systems with fast gain recovery. The interplay between cavity dispersion and phase sensitive non-linearities is shown to significantly impact the laser emission behavior.

Summary: We investigate the behavior of nonlinear periodic and solitary two-dimensional rolling waves in a falling two-layer liquid film with nonzero Reynolds numbers. We find that the film is linearly unstable and supports neutral stable waves in the form of zigzag surface modes and thinning varicose interface modes. By reducing the Navier-Stokes equation, we study the onset, bifurcations, and interactions of nonlinear periodic traveling waves. Solitary waves with droplets and depressions are observed, and their characteristics are derived from homoclinic loops. The dynamics of wave interactions are discovered to be influenced by coarsening and competition between different types of waves, leading to the formation of a quintessentially two-layer dynamical regime with a ruptured second layer.

Summary: Mean-field theory-based models are commonly used for designing optical metamaterials. However, for applications involving layered device architectures, the dispersive properties and interfacial boundary conditions of the metamaterials need to be considered. In this study, we propose a method to calculate the optical transfer function for one-dimensional optical metamaterials, taking into account the dispersive properties of the effective index and the effective interfacial impedance.
