Exciton migration in two-dimensional materials
Excitons play an essential role in the optical response of two-dimensional materials. These are bound states showing up in the band gaps of many-body systems and are conceived as quasiparticles formed by an electron and a hole. By performing real-time simu ...
Nature Portfolio2024Single-frequency violet and blue laser emission from AlGaInN photonic integrated circuit chips
Tobias Kippenberg, Anat Siddharth
Chip-based, single-frequency and low phase-noise integrated photonic laser diodes emitting in the violet (412 nm) and blue (461 nm) regime are demonstrated. The GaN-based edge-emitting laser diodes were coupled to high-quality on-chip micro-resonators for ...
Optica Publishing Group2023Metasurface-stabilized optical microcavities
Cavities concentrate light and enhance its interaction with matter. Confining to microscopic volumes is necessary for many applications but space constraints in such cavities limit the design freedom. Here we demonstrate stable optical microcavities by cou ...
NATURE PORTFOLIO2023Sub-kHz-Linewidth External-Cavity Laser (ECL) With Si3N4 Resonator Used as a Tunable Pump for a Kerr Frequency Comb
Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers (ECL), offering wideband tunability along with low optical linewidths. Exter ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Linear and nonlinear applications of miniaturized silicon nitride microresonators
Photonic integrated circuits (PICs) are the subject of massive interest due to the range of applications they can provide at a huge scale while building on well-established CMOS technologies. One of the critical parameters defining a technology's maturity ...
EPFL2023Resonators with tailored optical path by cascaded-mode conversions
Ileana-Cristina Benea-Chelmus, Marco Piccardo
Optical resonators enable the generation, manipulation, and storage of electromagnetic waves. The physics underlying their operation is determined by the interference of electromagnetic waves, giving rise to the resonance spectrum. This mechanism causes th ...
NATURE PORTFOLIO2023InP/Si3N4 Hybrid External-Cavity Laser with sub-kHz Linewidth Acting as a Pump Source for Kerr Frequency Combs
We report on an InP/Si3N4 hybrid integrated ECL that relies on 3D-printed coupling elements such as intra-cavity photonic wire bonds and facet-attached microlenses. We demonstrate 90 nm tuning range, SMSR above 60 dB, and intrinsic linewidths of 979 Hz. We ...
