Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

Advanced Functional Materials, Volume 36, Issue 91, 12 November 2026.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Direct laser written couplers with shifted bragg gratings

, 2015
We realize high-precision control over the lateral shift between Bragg gratings in directional waveguide couplers fabricated by direct-laser writing in glass and demonstrate the potential for spatiotemporal control of slow-light pulses at ...

Optical‐Field Engineering and Instrumentation in Brillouin Microscopy

Advanced Photonics Research, Volume 7, Issue 11, November 2026.
Brillouin microscopy provides label‐free mechanical contrast through gigahertz light–acoustic interactions. This Review examines how optical‐field engineering and instrument architecture shape spectral precision, acquisition throughput, background rejection, spatial performance, and optical exposure.
