    Design of a high-performance optical tweezer for nanoparticle trap**

    Integrated optical nanotweezers offer a novel paradigm for optical trap**, as their ability to confine light at the nanoscale leads to extremely high gradient forces. To date, nanotweezers have been realized...

    Triggering extreme events at the nanoscale in photonic seas

    Hurricanes, tsunamis, rogue waves and tornadoes are rare natural phenomena that embed an exceptionally large amount of energy, which appears and quickly disappears in a probabilistic fashion. This makes them d...

    Observation of soliton compression in silicon photonic crystals

    Solitons are nonlinear waves present in diverse physical systems including plasmas, water surfaces and optics. In silicon, the presence of two photon absorption and accompanying free carriers strongly perturb ...

    Integrated spatial multiplexing of heralded single-photon sources

    The non-deterministic nature of photon sources is a key limitation for single-photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single-photon yield without enhancing the ...

    Enhanced energy storage in chaotic optical resonators

    Chaos is a phenomenon that occurs in many aspects of contemporary science. In classical dynamics, chaos is defined as a hypersensitivity to initial conditions. The presence of chaos is often unwanted, as it in...

    Green light emission in silicon through slow-light enhanced third-harmonic generation in photonic-crystal waveguides

    Slow light has attracted significant interest recently as a potential solution for optical delay lines and time-domain optical signal processing1,2. Perhaps even more significant is the possibility of dramaticall...

    Beam steering in planar photonic crystal based on its anomalous dispersive properties

    We utilize the anomalous dispersion of planar photonic crystals near the dielectric band edge to control the wavelength-dependent propagation of light. We typically observe an angular swing of up to 10° as the...

    Reprocessing of thermally oxidized aluminum arsenide (AlAs) in epitaxial multilayers without delamination

    Annealing or processing of AlAs that has been subjected to a wet thermal oxidation process can result in severe delamination of material at the oxidation front. This paper reports a procedure for preventing th...

    Finite-depth and intrinsic losses in vertically etched two-dimensional photonic crystals

    We address the issue of out-of-plane losses in two-dimensional (2D) photonic crystals (PC) etched through a GaAs monomode waveguide clad with standard GaAlAs alloys. We correlate experimental transmission of P...

    Transmission properties of two-dimensional photonic crystal channel waveguides

    We study the transmission properties of straight channel waveguides designed in a two- dimensional (2D) photonic crystal patterned into an AlGaAs heterostructure. 2D dispersion calculations show the existence ...
