Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Mode‐Locked Pulse Generation in Plasmonic Lattices

Laser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Formation of ultracold RbCs molecules by photoassociation

, 2011
The formation of ultracold metastable RbCs molecules is observed in a double species magneto-optical trap through photoassociation below the ^85Rb(5S_1/2)+^133Cs(6P_3/2) dissociation limit followed by spontaneous emission.

Digitally Tunable Dispersion Controller Using Low‐Loss Silicon Nitride Multimode Waveguide Gratings

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
A digitally tunable dispersion controller (DTDC) using low‐loss silicon nitride multimode waveguide gratings is demonstrated. Utilizing cascaded chirped multimode waveguide gratings and Mach–Zehnder switches, the device achieves a tuning range of 0–49.72 ps/nm with 1.60 ps/nm steps over a 26‐nm bandwidth.
