Abstract We show that nearly-degenerate Vertical External-Cavity Surface-Emitting Lasers may emit a set of tilted beams of individually addressable mode-locked pulses. These time localized beams feature a Gaussian profile and they are emitted in pair

Two experimental implementations of the double-cantilever beam experiment, developed to measure the bonding energy in wafer-bonded semiconductors, are compared for the first time. The comparison is carried out in two material combinations relevant to

The mechanical stability of commercial GaP/Si templates during thermal an-nealing and subsequent MOCVD growth of GaP and AlGaP is investigated.Although the GaP layer of the template originally presents an excellent surfacemorphology, annealing at hig

Spatiotemporal mode-locking is a promising lasing regime for developing coherent sources for multimode nonlinear photonics. In this paper we show that large-aspect-ratio vertical external-cavity surface-emitting lasers (VECSELs) can be operated in th

We fabricated a Ge 0.92 Sn 0.08 micro-disk laser with a lasing threshold as low as 20-30 kW/cm2 at 75 K. A specific etching process was developed to remove the dense array of misfit dislocations from the gain medium. Further surface treatments and pa

All-dielectric optical metasurfaces consist of 2D arrangements of nanoresonators and are of great importance for shaping polarization, phase and amplitude of both linear and harmonic fields. Here, we demonstrate the generation of second harmonic (SH)

Lasing in bulk GeSn alloys have been reported lately with relatively high thresholds in the range of several hundreds of kW/cm². This can be mainly attributed to high defect densities of high Sn content alloy thick layers grown on relaxed Ge-VS. Ind
