Sensor Electronic Technology, Inc. (SET, Inc.)_ is emerging as a leading commercial supplier of Light Emitting Diodes (LEDs) with peak emission wavelengths below 365 nm. Recently, we have demonstrated 280 nm wavelength LEDs with the record 0.9% wall-plug efficiency capable to deliver CW power of 2 mW at 50 mA [1] current and maximum pulsed power up to 49 mW at 1.3 A current and 10 mW pulsed power at 265 nm wavelength. [2] We will present our results on the development of Light Emitting Diodes (LEDs) with peak emission in the range from 265 nm to 365 nm and scale-up of this technology to 2” diameter wafers for volume manufacturing.
