We describe the first demonstration and characterization of an optically integrated InP-Si3 N4 hybrid laser. The laser is formed by integration of an InP-based reflective semiconductor optical amplifier with a InP-Si3 N4 based feedback waveguide circ

We record the two-dimensional laser-induced fluorescence (LIF) on multiple plasma constituents in a YBiO3 plasma. This allows us to directly link the influence of oxygen present in the background gas during pulsed laser deposition to the oxidation of

By applying two-dimensional laser induced fluorescence (LIF) on multiple plasma constituents, we are able to directly link the oxidation of plasma species in a SrTiO3 plasma for pulsed laser deposition to the stoichiometry and quality of the thin fil

Hybrid integrated diode lasers offer a robust and small-sized solution for applications in telecommunications, quantum optics and metrology due to their wide tunability and ultra-narrow linewidth. Here, we present the fabrication, packaging and succe

Extending the cavity length of diode lasers with feedback from Bragg structures and ring resonators is highly effective for obtaining ultra-narrow laser linewidths. However, cavity length extension also decreases the free-spectral range of the cavity

We present a general method for designing XUV aperiodic multilayer mirrors that can mimic a given target spectrum, specifically, the spectral transmission of an XUV optical system. The method is based on minimizing a merit function and using fidelity

Silicon nitride (Si 3 N 4 ) waveguides offer a versatile on-chip platform, on which nonlinear processes such as four-wave mixing (FWM) can be driven very efficiently due to the high nonlinearity [1] . Therefore, lower pump energies and shorter intera
