Introduction to Flat Top Piranha LED Diodes

Flat Top Piranha LED diodes are a type of light-emitting diode (LED) that emit light at a specific wavelength, typically in the ultraviolet (UV) or visible spectrum. The term "flat top" refers to the emission profile of the LED, which has a relatively uniform intensity across the entire emitting area. This distinct characteristic makes flat top piranha LED diodes highly desirable for various applications, including spectroscopy, fluorescence microscopy, and laser technology.

How Flat Top Piranha LED Diodes Work

Flat top piranha LED diodes operate based on the principle of electroluminescence, where an electric current is applied to a semiconductor material, causing it to emit light. The semiconductor material used in these diodes is typically a combination of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs), which allows for the emission of light at specific wavelengths. The key to achieving a flat top emission profile lies in the design of the LED structure. A typical flat top piranha LED diode consists of a p-n junction, where the p-type and n-type regions are separated by a thin layer of GaAs. This structure allows for the confinement of the charge carriers, which results in the emission of light with a narrow bandwidth and a flat top profile.
