Frontiers of Bright CEP‐Stable Broadband Infrared Sources

Laser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

Laser &Photonics Reviews, EarlyView.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

Laser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Black Phosphorus/Ferroelectric CuInP2S6 Heterostructures Empowering Nonvolatile Photonic Convolutional Computing

Laser &Photonics Reviews, EarlyView.
ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Macromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

Polymeric Optical Waveguides

SPIE Proceedings, 1990
Summary The challenges for introducing optical waveguides into the high performance computer packaging environment are formidable. Polymers may be well suited for meeting this challenge. In this work, progress was shown using an epoxy material vT hich has been fabricated into ridge waveguides which exhibit low propagation loss (0.3 dB/cm at 1.3 jum ...

Optical Waveguide Refractometers

2005
In this chapter we have illustrated a new method for the determination of the refractive index of liquid samples, based on Cerenkov second harmonic generation from suitable planar waveguides. The method allows the determination of the refractive index in the near infrared by detection in the visible.
