Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser

Laser &Photonics Reviews, EarlyView.
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals

Laser &Photonics Reviews, EarlyView.
The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

Plasmon–Exciton Coupling Enhances Second‐Order Nonlinear Response in Borophene–ZnO Hybrid Structures

Laser &Photonics Reviews, EarlyView.
Nonlinear interactions between plasmons in borophene and excitons in ZnO lead to enhanced nonlinear and incoherent cathodoluminescence, as well as coherent second harmonic generation, under electron‐beam and laser irradiations, respectively. The anisotropic response of borophene, revealed as in‐plane hyperbolic polariton propagation, acts as a control ...

Frequency comb-linked mid-infrared continuous-wave optical parametric oscillator

, 2014
We report on a frequency comb-referenced mid-infrared continuous-wave optical parametric oscillator. The frequency of the mid-infrared idler beam is locked to a near-infrared frequency comb after frequency doubling the idler ...

Chip Scale Emission of Blue Light at Elevated Temperatures in Optical Waveguides Integrated With Rubidium Vapor

Laser &Photonics Reviews, EarlyView.
An integrated atom‐clad waveguide enables chip‐scale blue light generation (420 nm) via a two‐photon ladder transition in rubidium vapor at temperatures up to 240°C. The observed bell‐shaped intensity profile reveals a competitive interplay between local photon generation and macroscopic vapor reabsorption.

Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

Laser &Photonics Reviews, EarlyView.
Independent control of the repetition rate and offset frequency is demonstrated in quantum cascade laser frequency combs using radio‐frequency injection and thermal tuning. A revised comb model anchored at optical frequencies captures the unique behavior under radio‐frequency injection and enables precise frequency control.
