Laser &Photonics Reviews, EarlyView.Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network
Laser &Photonics Reviews, EarlyView.This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Laser &Photonics Reviews, EarlyView.Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, EarlyView.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

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 ...
