Market Growth Factors
The growing need for miniaturization of laser diodes is one of the key factors driving this market’s growth. With advances in technology, laser diodes are increasingly being used in smaller electronic devices such as smartphones, tablets, and wearables. In addition to laser autofocus and gesture recognition systems, the development of small laser diodes has led to the integration of lasers in medical applications including point-of-care diagnostics, minimally intrusive surgery, and portable medical devices.
The energy and power sector is also propelling market growth, since laser diodes are used in solar energy harvesting, laser power transmission, scribing, cutting, and structuring solar cells which help to improve performance and efficiency of solar cells. Another growing field in renewable energies, laser wireless power transfer and laser energy transmission technologies may also use laser diodes increasing the number of applications in the laser diode market.
Another driving force behind the laser diode industry is the increasing use of laser diodes in fiber optic communication networks. Such networks need efficient, high-speed light sources for long-distance data transmission. The combination of high output power, broad wavelength range and fast modulation speed makes laser diodes good candidates for broadband applications. As the internet, cloud computing and streaming have grown, so too has the demand for laser diodes in telecommunications.
