Direct Orientation Contrast Imaging of Anti-Phase Domains on III-V Materials Using Scanning Electron Microscopy
Brieg Le Corre, Clothilde Grenèche, Rozenn Bernard +16
Direct orientation contrast imaging of zinc-blende III-V materials is studied using scanning electron microscopy. A quantitative approach is taken using a 3 μm thick orientation-p…
Time-Resolved dynamics of semiconductor nanolaser via four-wave mixing gating
Federico Monti, Guilhem Madiot, Giuseppe Modica +5
We experimentally demonstrate the direct time-domain characterization of photonic-crystal nanolasers at telecom wavelengths using a nonlinear optical gating technique based on four…
Accurate prediction of optical transitions in epitaxial InGaAs/InAlAs asymmetric coupled quantum well structures
Konstantinos Pantzas, Virginie Trinité, Angel Vasanelli +5
Atomically-resolved Z-contrast and strain mappings are used to extract a model of the composition of an InGaAs/InAlAs asymmetric coupled quantum-well structure grown on InP using m…
Mid-infrared integrated resonators on a III-V platform with Q-factors beyond half a million
Luca Lucia, Gia Long Ngo, Mathilde Urbain +7
We demonstrate mid-IR integrated race-track resonators on a III-V semiconductor platform,InGaAs core epitaxially grown on InP. We have performed a complete characterization of the…
High efficiency second harmonic generation in transverse orientation patterned gallium phosphide waveguides
Antoine Lemoine, Brieg Le Corre, Lise Morice +13
Achieving high conversion efficiencies in second-order nonlinear optical processes is a key challenge in integrated photonics for both classical and quantum applications. This pape…
Mid-Infrared Frequency Combs and Pulse Generation based on Single Section Interband Cascade Lasers
Pavel Abajyan, Baptiste Chomet, Daniel A. Diaz-Thomas +10
Interband Cascade Lasers (ICLs) are semiconductor lasers emitting in the mid-wave infrared (MWIR 3-6 μm) and can operate as frequency combs (FCs). These demonstrations are based o…
