Recent progress in III-V nanowire (NW) light sources integrated onto Si (quantum) photonic circuits is presented, illustrating key results for low-threshold vertical-cavity NW-lasers and integrated NW-quantum emitters with efficient light coupling to

Recent demonstrations of direct integration of GaAs-based nanowire lasers on Si photonic circuits exhibited efficient in-coupling of lasing emission to proximal waveguides - however, transmission in the Si waveguide suffered from high absorption loss

Realizing telecom-band lasing in GaAs-based nanowires (NW) with low bandgap gain media has proven to be notoriously difficult due to the high compressive strain built up in the active regions. Here, we demonstrate an advanced coaxial GaAs-InGaAs mult

Semiconductor nanowire (NW) lasers are attractive as integrated on-chip coherent light sources with strong potential for applications in optical communication and sensing. Realizing lasers from individual bulk-type NWs with emission tunable from the

We demonstrate lasing from individual GaAs-based NWs integrated onto Si ridge waveguides. In addition, proof-of-principle coupling emission to the Si WG is shown, with propagation distances of the lasing mode exceeding > 60 pm

In this paper, we generalise the treatment of isolated horizons in loop quantum gravity, resulting in a Chern-Simons theory on the boundary in the four-dimensional case, to non-distorted isolated horizons in 2(n+1)-dimensional spacetimes. The key ide

Supergravity was originally introduced in the hope of finding a theory of gravity without the shortcoming of perturbative non-renormalisability. Although this goal does not seem to have been reached today (with the possible exception of d = 4, N = 8

We show that under certain technical assumptions, including the existence of a constant mean curvature (CMC) slice and strict positivity of the scalar field, general relativity conformally coupled to a scalar field can be quantised on a partially red
