ꟻLIP‐Based Perceptual Optimization for Subpixel Rendering Filters

open access: yesJournal of the Society for Information Display, EarlyView.
We propose a two‐stage subpixel rendering framework combining MMSE‐based initialization and ꟻLIP‐guided perceptual optimization. The kernel is refined by minimizing the mean ꟻLIP error using a Nelder‐Mead optimizer to reduce perceptual distortion beyond RGB‐based methods.

High‐Efficiency and Long‐Lifetime Narrowband Green MR‐TADF OLEDs Enabled by Distinct Molecular Design Strategies

open access: yesJournal of the Society for Information Display, EarlyView.
Two complementary molecular design strategies are proposed to independently enhance operational stability and device efficiency in MR‐TADF OLEDs. Strengthening the cationic bond dissociation energy (BDEf+) improves intrinsic molecular robustness and prolongs device lifetime, although a PSF‐based efficiency‐oriented design with high molar absorption ...

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

open access: yesLaser &Photonics Reviews, EarlyView.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

open access: yesLaser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Evapotranspiration at Kilometre Scale using a Bi-Chromatic Scintillometer System

open access: yes, 2012
Scintillometry has become a generally accepted technique to obtain area-averaged turbulent fluxes at the 0.1 – 10 km scale. Optical large aperture scintillometers (LAS) that yield the sensible heat flux (H) have been tested under a wide range of circumstances (De Bruin, 2002) and are commercially available.
