/en/media-center/media-review/fbh-to-present-novel-lasers-at-photonics-west
At Photonics West 2025 in San Francisco (January 25-30, 2025), the Ferdinand-Braun-Institut (FBH) will be presenting novel and advanced diode lasers.
Investigating Transient Thermal Response of High-Power, High-Duty-Cycle Diode Laser Stacks using FEA-Based Simulation
/en/research/publications/investigating-transient-thermal-response-of-high-power-high-duty-cycle-diode-laser-stacks-using-fea-based-simulation
The transient heat distribution within high-power edge-cooled diode laser stacks under high-duty-cycle pulsed operation is simulated using finite element analysis. The impact of varying pulse…
Analyses of degradation mechanisms in single mode InGaN based laser diodes
/en/research/publications/analyses-of-degradation-mechanisms-in-single-mode-ingan-based-laser-diodes
We investigated fabrication aspects of InGaN based laser diodes, such as substrate type, activation of p-type conductivity and facet coating with respect to the device reliability. Material analyses…
Improved efficiency and beam divergence in kW-class diode laser bars with edge-heaters
/en/research/publications/improved-efficiency-and-beam-divergence-in-kw-class-diode-laser-bars-with-edge-heaters
We present a novel approach to flattening the in-chip thermal profile that develops within multiple-emitter, 1-cm-wide bars by optimally manipulating heating at the edge-emitters. The best-designed…
Bragg Gratings Reflectance Prediction with Coupled Mode Theory Fitted to 2D FDTD
/en/research/publications/bragg-gratings-reflectance-prediction-with-coupled-mode-theory-fitted-to-2d-fdtd
This study explores a surrogate model using coupled mode theory to predict the reflectivity spectrum of surface Bragg gratings. We use 2D FDTD simulations to build and validate the surrogate model.…

FBH presents latest research results at the 2025 IEEE/SICE International Symposium on System Integrations.
Individual nanostructures in an epsilon-near-zero material probed with 3D-sculpted light
/en/research/publications/individual-nanostructures-in-an-epsilon-near-zero-material-probed-with-3d-sculpted-light
Epsilon-near-zero (ENZ) materials, i.e., materials with a vanishing real part of the permittivity, have become an increasingly desirable platform for exploring linear and nonlinear optical phenomena…

The EU Chips Act-funded pilot line for 'Advanced Packaging and Heterogeneous Integration for Electronic Components and Systems' (APECS) has begun operation providing large industry players, SMEs, and…
Flat dispersion at large momentum transfer at the onset of exciton polariton formation
/en/research/publications/flat-dispersion-at-large-momentum-transfer-at-the-onset-of-exciton-polariton-formation
Excitons are quasiparticles, comprised of an electron excited from the valence band and attracted to the hole left behind, that govern transport properties in transition metal dichalcogenides.…
