Theory of quantum frequency translation of light in optical fiber: application to interference of two photons of different color

, 2011
We study quantum frequency translation and two-color photon interference enabled by the Bragg scattering four-wave mixing process in optical fiber. Using realistic model parameters, we computationally and analytically determine the Green function and ...

Highly Efficient Color Conversion of 3D Photonic Crystal Phosphor Films for Micro‐Light‐Emitting Diode Applications

Advanced Photonics Research
The color conversion efficiency of phosphor films can be significantly improved by producing them in the shape of photonic crystals (PhCs). When light with photonic band‐edge wavelengths is incident on a PhCs phosphor film, the excitation photons are ...

Increasing Color Quality of Red Emperor Snapper Lutjanus Sebae Seed Through Enriched Diet with Red Fruit Pandanus Conoideus Oil as Beta-caroten Source [PDF]

, 2012
Market price of red emperor snapper Lutjanus sebae is often determined by its color performance. Adding beta-carotene on a fish diet would possibly escalate red pigmentation. Oil from a red fruit (Pandanus conoideus, Lam) known as potential beta-carotene

NEW PHENOMENON OF COLOR CONVERSION. [PDF]

Journal of the American Medical Association, 1906
It is several years since I first observed and instituted some experiments with an interesting color conversion phenomenon which, so far as I could learn, had previously been unobserved. After some thought and examination regarding the phenomenon I communicated it to Dr. George T.

Model Calculation of Enhanced Light Absorption Efficiency in Two-Dimensional Photonic Crystal Phosphor Films

Photonics
When a phosphor film based on a photonic crystal (PhC) is excited at the photonic band-edge wavelength, the absorption of excitation light increases, which can potentially enhance the color-conversion efficiency.
