Development History of Broadband IR LEDs

Broadband IR LEDs have a long history of development. The earliest infrared LEDs were developed in the 1960s, mainly used in remote control and other applications. In the 1970s, with the continuous development of semiconductor technology, the brightness and efficiency of infrared LEDs were significantly improved. In the 1980s, the development of infrared communication technology promoted the application of infrared LEDs in consumer electronics. The early infrared LEDs were mainly in the 940nm band, which had a narrow bandwidth and limited transmission distance.

In the 1990s, with the rapid development of optoelectronic technology, the research and development of broadband IR LEDs began. The introduction of quantum well structures and other novel semiconductor materials made it possible to produce broadband IR LEDs with a wide bandwidth and longer transmission distance. In the 2000s, the application of broadband IR LEDs has been expanded to more fields, such as automotive, industrial, and medical fields.
