Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators
Small, EarlyView.The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Small Methods, EarlyView.An advanced patterning method is presented for metal‐assisted chemical etching. The interlayer replaces the resist and enables catalyst deposition on a clean interface. The prepared samples show improved performance with a more reproducible etching profile, higher aspect ratio, and increased consistency over a larger area.

Nanophotonics, Volume 15, Issue 15, 13 August 2026.A 400 nm graphene oxide film on a beam‐expanding fiber facet is patterned by femtosecond laser direct writing into a 19‐lens microlens array. The device simultaneously splits a single input beam into multiple 0.67–0.74 NA focus spots with a broadband response from 850 to 1550 nm.

Nanophotonics, Volume 15, Issue 15, 13 August 2026.Optomechanical frequency combs are generated in high‐Q microbubble cavities by simultaneous ultrasound and laser excitation, arising from nonlinear coupling between optomechanical modes and ultrasonically driven mechanical oscillations. Comb spacing and intensity are tunable through acoustic and optical parameters, whereas the optical spring effect ...

Radiation‐Free In‐Gap Finite Barrier Bound States in a Lithium Niobate‐Based Honeycomb Lattice
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work demonstrates radiation‐free finite barrier bound states (FBBSs), successfully overcoming the high propagation loss challenge inherent in conventional FBBS designs while enabling flexible electro‐optic tunability. These findings establish a versatile platform for on‐chip integrated, high‐modulation‐efficiency electro‐optic modulators and ...
