In this review, the concept of open cavity lasing for ultrasensitive sensing is explored,
specifically in driving important innovations as laser-based biosensors─ a field mostly …

Chip‐scale, electrically‐pumped terahertz (THz) frequency‐combs (FCs) rely on nonlinear
four‐wave‐mixing processes, and have a nontrivial phase relationship between the evenly …

Near-field imaging techniques, at terahertz frequencies (1–10 THz), conventionally rely on
bulky laser sources and detectors. Here, we employ a semiconductor heterostructure laser …

Optical resonators are fundamental building blocks of photonic systems, enabling meta-

Excitation of Dirac plasmon polaritons (DPPs) in bi‐dimensional materials have attracted
considerable interest in recent years, both from perspectives of understanding their physics …

In this article, we revisit the concept of optical feedback regimes in diode lasers and explore
each regime experimentally from a somewhat unconventional point of view by relating the …

Mode locking, the self‐starting synchronous oscillation of electromagnetic modes in a laser
cavity, is the primary way to generate ultrashort light pulses. In random lasers, without a …

In this opinion article, I summarize some of the recent developments in the field of near-field
