Relayed-loop optical scan amplification
Many modern sensing, processing, and fabrication technologies depend upon the sequential scanning of laser light. Due to inertial, thermal, and electrical limitations, the speed of a typical laser deflector is inversely related to its optical invariant and therefore the number of resolvable spots it can address. Passive optical systems have been developed that can effectively double the optical invariant and maximum throughput of a single deflector. We present a method for increasing the effect…

Topological photonics, which harnesses topologically nontrivial structures to support defect-robust photonic states, offers a promising solution to this challenge. Here, we demonstrate a topological laser that is one-step nanoimprinted upon colloidal perovskite nanocrystals. Th…

Cavity-enhanced symmetric second-harmonic generation
As one of the two types of backward second-harmonic generation (SHG), symmetric SHG exhibits some physical characteristics and application prospects that are distinct from those of forward SHG. It is generally realized through quasi-phase matching, which imposes more stringent requirements on the poling period and thus presents challenges for domain engineering. Although employing larger poling periods can ease fabrication, it inevitably reduces conversion efficiency, a drawback that can be com…
