Highly Efficient Intramodal and Intermodal Acousto‐Optic Modulation on an Etchless Lithium Niobate Integrated Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Harnessing light–sound interaction in photonic integrated circuits can enable many classical and quantum applications on a chip. By utilizing bound states in the continuum for ultralow‐loss waveguiding, highly efficient intramodal and intermodal acousto‐optic modulation is demonstrated on an etchless lithium niobate integrated platform in the ...

Continuous‐Wave Laser‐Driven Cascaded Harmonic Generation in a Periodically Poled Lithium Niobate Racetrack Resonator

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates efficient continuous‐wave‐driven cascaded harmonic generation up to the ultraviolet in a periodically poled thin‐film lithium niobate racetrack resonator. Using a single poling period and telecom‐band laser input, the device achieves second harmonic generation with 2,200% W−1${\rm W}^{-1}$ efficiency and supports third and fourth

Enhanced Rabi Splitting of Exciton‐Polaritons and Plasmon‐Polaritons in Lithium Niobate Metasurface

open access: yesLaser &Photonics Reviews, EarlyView.
This study presents an ultrathin lithium niobate metasurface capable of inducing highly sensitive Fano‐shaped resonances, enabling strong coupling with TMDC monolayers and plasmonic metamaterials/metasurfaces. Adjustable Q‐factors lead to controllable coupling strengths, achieving substantial Rabi splitting.

Dynamics of Vector Soliton Singlets and Pairs in Self‐Mode‐Locked Tm‐Doped Fibre Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
This study characterises soliton build‐up dynamics in a self‐mode‐locked Tm‐doped fibre laser, where both cavity birefringence and distributed saturable absorber play significant roles in the intracavity pulse shaping. The recorded single‐shot spectra using the dispersive Fourier transform technique reveal intensity‐dependent temporal splitting of ...

Dynamics of Dissipative Cavity Solitons in a Lattice Trap

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.
