Infrared LED and laser diode: technology, application and industrial trend

according to the consulting introduction of maims, infrared light emitting diode (IR LED) and laser diode (LD) are not new technologies, which were born as early as the 1960s. However, recently, with the development of solid-state lighting (SSL), it has risen rapidly. LED and LD were originally developed for optical communication applications. Now they have been widely used in data communication/telecommunications, consumer electronics, automotive and industrial fields to achieve more high-value functions

infrared light sources are classified according to wavelength

various LED and LD products have found their own development path:

- IR LED initially focused on low-end applications, such as photoelectric circuit breakers, remote controllers, etc., but now it is increasingly used in proximity sensing in intelligence, gesture recognition in cars, eye tracking in virtual reality (VR) and augmented reality (AR) devices

- the edge emitting laser (eel) market has always been driven by optical communication applications. As the amount of data exchanged with the optical fiber network continues to grow, the eel market will continue to benefit. However, growth drivers may also be found in new applications in the future, such as lidar

- the vertical cavity surface emitting laser (VCSEL) was used in short-range data communication in the early stage. However, the iPhone x released by apple in 2017 integrates the 3D sensing function based on VCSEL, which has completely changed the commercialization prospect of VCSEL, making it the fastest-growing solid-state light source technology in the current market and attracting a large number of funds

main application development of VCSEL, eel, IR LED

these infrared solid-state light sources have different semiconductor structures, and the epitaxy and semiconductor processes adopted are also different. They output at different wavelengths/powers and provide different luminous contours/shapes, thus forming a variety of product specifications to meet the needs of different applications. With the increasing interest in photon technology in the automotive and consumer fields, the prospect of infrared lighting applications is bright

infrared light source market: it is expected to reach US $6.5 billion in 2023

at present, more than 40 applications have integrated infrared solid-state light sources. Some of these applications are expected to promote the vigorous development of IR LED and LD markets in the next five years

optical communication is one of the oldest applications of infrared light sources. Now, due to the explosive growth of Internet data and the emergence of IOT, cloud services and autonomous vehicle, it will continue to drive the infrared light source market

driven by the application of additive materials, the industrial application of infrared light sources also hopes to generate high profits in the next few years. Traditional infrared light sources (such as IR LED) began to be replaced by VCSEL, which can reduce power consumption

3d sensing is becoming a "killer" Application of infrared light sources. The 3D face recognition application of VCSEL in Apple iPhone X has aroused great interest, and many Android manufacturers have followed apple in releasing smart new products integrated with VCSEL. However, 3D sensing technology can be used not only for face recognition, but also for car lidar, which is a necessary technology for automatic driving! Therefore, the field of 3D sensing has attracted many start-ups and set off a wave of 3D visual revolution

to sum up, the infrared light source market is expected to reach $1.8 billion in 2018 and $6.5 billion in 2023, with a compound annual growth rate of 29%

the word-of-mouth of Jinan new era Gold Testing Instrument Co., Ltd. the composite polyurethane adhesive industry is a technology intensive industry, which inherits the standardized services from the gold testing

infrared light source market forecast

infrared light source industrial structure and maturity

driven by the application of visible light lighting, today's LED industry is quite mature. Almost all manufacturers adopt the vertical integration mode: from extension to packaging. In this industry, we have studied more than 40 IR LED suppliers, most of which are from Asia. In addition to high-power and long/multi wavelength IR LED products, the manufacturing process is well controlled and the remaining technical challenges are less

eel and VCSEL are completely different from IR LED in terms of the loading speed of the abetting pointer and the speed and loading speed of the abetting plate. Most manufacturers are from the United States and Europe. The manufacturing process is also much more complex, and R & D and engineering technology are still needed to improve equipment performance and capacity. Therefore, there are various types of participants in the industrial chain: EPI houses, foundries, integrated component manufacturers (IDM), fabless, etc

industrial ecosystem (major manufacturers) of infrared light sources (LED, VCSEL, eel)

in this context, professional manufacturers (mainly epitaxial plants, foundries and fabless companies) still have great business opportunities because eel and VCSEL will become the main driving force of the future infrared lighting market. This is mainly related to "the manufacturing process still needs to be optimized" and "the challenge of integrating infrared light sources into modules or systems". Polaris was launched last October. In fact, eel and VCSEL can be combined with complex optical devices, such as dot matrix projectors for 3D face recognition
