Technology Behind High Power 780 nm LEDs

The technology behind high power 780 nm LEDs involves the use of advanced semiconductor materials and manufacturing processes. These LEDs are typically made using gallium nitride (GaN) as the active layer, which is capable of emitting light at the desired 780 nm wavelength. The key to achieving high power output lies in the design of the LED structure, which includes the use of multiple quantum wells and antireflection coatings to enhance light extraction.

Manufacturing Process

The manufacturing process of high power 780 nm LEDs involves several critical steps. First, a p-type GaN layer is deposited on a sapphire or silicon carbide (SiC) substrate. Then, a series of n-type and p-type GaN layers are grown on top, forming the active region. This is followed by the insertion of multiple quantum wells, which are designed to increase the electron-hole recombination rate and thus the light emission. Finally, the LED is encapsulated with a phosphor layer to convert the blue light emitted by the LED into the desired red light.
