How to distinguish elastically scattered light from Stokes shifted light for solid-state lighting?

Printed Inorganic Light Emitting Diodes for Solid State Lighting

In this paper we present a new form of inorganic printed electronics (PE) that overcomes many of the problems associated with the act of printing electronics. The technique allows for very high speed, inexpensive production of PE products. To illustrate this approach we will describe a solid state lighting (SSL) device based upon a standard InGaN heteroepitaxy and fabricated as micro LEDs dispe...

Discrimination between Doppler-shifted and non-shifted light in coherence domain path length resolved measurements of multiply scattered light.

We show a novel technique to distinguish between Doppler shifted and unshifted light in multiple scattering experiments on mixed static and dynamic media. With a phase modulated low coherence Mach- Zehnder interferometer, optical path lengths of shifted and unshifted light and path length dependent Doppler broadening are measured in a two-layer tissue phantom, with a superficial static layer of...

Solid-state light-phase detector

Attosecond science relies on the use of intense, waveform-controlled, few-cycle laser pulses1 to control extreme nonlinear optical processes taking place within a fraction of an optical period. A number of techniques are available for retrieving the amplitude envelope and chirp of such few-cycle laser pulses. However, their full characterization requires detection of the absolute offset between...

APPLIED PHYSICS REVIEWS—FOCUSED REVIEW High-efficiency AlGaInP light-emitting diodes for solid-state lighting applications

AlGaInP lattice matched to GaAs is suited for light-emitting diodes ~LEDs! operating in the red, orange, yellow, and yellow–green wavelength range. Such long-wavelength visible-spectrum devices will play an important role in solid-state lighting applications. This review discusses the major classes of AlGaInP device structures, including absorbing-substrate ~AS! LEDs, absorbing substrate LEDs e...
