Depth Control of Room-Temperature Quantum Emitters in Gallium Nitride
Alexandros Bampis, Johann Stachurski, Anna Schwab +3
Bright quantum emitters are key components for quantum communication systems. Radiative point defects in gallium nitride (GaN) are promising candidates for room-temperature single-…
Three-Octave Supercontinuum Generation in Thick Crystalline Aluminum Nitride Waveguides
Samantha Sbarra, Samuele Brunetta, Pierre Arnaud Demongodin +4
We report an efficient extension of supercontinuum generation through dispersion engineering of crystalline aluminum nitride (AlN)-on-sapphire waveguides. Using a tailored epitaxia…
Sputtered AlN buffer layer for low-loss crystalline AlN-on-sapphire integrated photonics
Samuele Brunetta, Samantha Sbarra, Brandon Shuen Yi Loke +4
In recent years, aluminum nitride (AlN) has emerged as an attractive material for integrated photonics due to its low propagation losses, wide transparency window, and presence of…
Thermal analysis of GaN-based photonic membranes for optoelectronics
Wilken Seemann, Mahmoud Elhajhasan, Julian Themann +11
Semiconductor membranes find their widespread use in various research fields targeting medical, biological, environmental, and optical applications. Often such membranes derive the…
Excitonic interplay between surface polar III-nitride quantum wells and MoS monolayer
Danxuan Chen, Jin Jiang, Thomas F. K. Weatherley +3
III-nitride wide bandgap semiconductors exhibit large exciton binding energies, preserving strong excitonic effects at room temperature. On the other hand, semiconducting two-dimen…
Optical and thermal characterization of a group-III nitride semiconductor membrane by microphotoluminescence spectroscopy and Raman thermometry
Mahmoud Elhajhasan, Wilken Seemann, Katharina Dudde +9
We present the simultaneous optical and thermal analysis of a freestanding photonic semiconductor membrane made from wurtzite III-nitride material. By linking micro-photoluminescen…
