  • The concept of temporal mode-locking has been leveraged to study the interplay between laser mode-locking and photonic lattices that exhibit non-Hermitian topological phenomena. The results suggest new opportunities to study nonlinear and non-Hermitian topological physics as well as potential applications to sensing, optical computing and frequency-comb design.

  • I argue that a surface emitting laser that remains single mode irrespective of its size, a scale-invariant laser, should of necessity also waste light at the edge. This is a fundamental departure from the Schawlow-Townes two-mirror strategy that keeps light away from mirrors and edges to preserve gain and minimize loss. The strategy was implemented in the recent discovery of the Berkeley Surface Emitting Laser (BerkSEL).

  • High-quality aluminium nitride (AlN) heteroepitaxial films are obtained by the controlled discretization and coalescence of columns using nanopatterned AlN/sapphire templates with regular hexagonal holes. The density of dislocation etch pits in the AlN heteroepitaxial films is reduced to approximately 104 cm–2, approaching the value of that in AlN bulk single crystals.
