Light Emitting Diodes: A light-emitting diode (LED) emits light when forward-biased current flows through it. LEDs are widely used in displays and indicators. Schottky Diodes: Schottky diodes, also known as barrier diodes or hot-carrier diodes, are often used in high-speed applications because ...
Presented is an LED device that produces white light by performing phosphor conversion on substantially all of the primary light emitted by the light emitting structure of the LED device. The LED device comprises a light emitting structure and at least one phosphor-converting element located to ...
The channel corresponding to the correct digit produces the highest output current. (b) Experimental (symbols) and calculated (lines) light-intensity dependent accuracies for the NB classifier (blue) and a reference device without binning (red). Full size image Furthermore, it is known that ...
The recent development of perovskite light emitting diodes (PeLEDs) has the potential to revolutionize the fields of optical communication and lighting devices, due to their simplicity of fabrication and outstanding optical properties. Here we demonstrate that PeLEDs can also be used in the field of...
Over the past decades, the development of fibre optic cables, which pass light waves carrying data guided by total internal reflection, has led to advances

How is LED used as a source of light? Light-Emitting Diodes (LED) are light sources utilizing diodes that emit light when connected in a circuit. The effect is a form of electro luminescence where LEDs release a large number of photons outward; the LED is housed in a plastic bulb, which...
and implanting two metallic layers applied to bias voltages have been proposed. When the applied voltages are adjusted, the intensity and phase of the emitted SHG light are manipulated at a wavelength of 10 µm, thus providing free-space propagation tuning. This method can be further applied...
Fluorescence images (100 ms exposure) were taken using a ×40 objective every second for 5 min of neuron cultures exposed to continuous 18 mW mm−2 light illumination from a light-emitting diode (LED) (Spectra X, Lumencore). After background subtraction, the average intensity per ...
Most of these devices rely on amplitude (intensity) interrogation in which a narrow-band illumination source, such as a light-emitting diode (LED), is tuned to the plasmonic resonance, and the intensity variations due to the spectral resonance shifts that are induced by local refractive index ...
