VCSELs offer reliability, high efficiency, precision, and high speed with cost effective solution. Blue and green vertical-cavity surface-emitting lasers are based on indium gallium nitride. The blue and green vertical-cavity surface-emitting lasers are fuelling the growth of the market of small photonics devices such as laser pico projectors. Additionally, blue and green VCSELs are expected to find usage in laser printers with high density and high speed optical disk, and full color displays among others.
VCSELs have found broad applications in bar code sensors; POF based home networking, atomic clock technology, and datacomm industry. The growth in these verticals is attributed to unbeatable characteristic of VCSELs such as high speed and low cost, compared to LEDs. With significant lower cost, portability, high speed, power savings, chip scale atomic clocks (CSAC) can be introduced to extensive series of innovative applications. Additionally, VCSELs have been used in the datacomm industry, owing to their high speed supporting capabilities such as 10/40/100 Gbps Ethernet, 16 Gbps FC data infrastructure links, thus boosting the growth of the global. Newer applications including chip-to-chip and board-to-board interfaces where density, data rates, and power limits are major constraints are deploying VCSELs, thus fuelling the market ahead.
With increasing demand for high speed data networks, the demand of VCSELs in-turn is expected to surge during the forecast period. Moreover, with growing demand of 1Gbps POF based home networking market, the data communication industry witnessed proliferation in demand of low cost VCSELs. As POF based home networking is a consumer product, the usage of lower cost VCSELs is anticipated to increase market penetration, which in-turn is propelling the growth of the VCSELs market.
Due to the restriction of escalating the rotational frequency of the polygonal mirror, an array of mirror is a way to make speed improvement. Therefore, VCSELs are preferred in Laser printers. The market has witnessed the usage of VCSELs in few high end laser printers; however, the exponential growth in use of VCSELs arrays is anticipated for laser printers manufacturers, in order to obtain an edge over others in a competitive environment.
The markets for VCSELs are proliferating swiftly as it has become the attractive choice for a number of high-volume applications. The increase in adoption of VCSELs across gesture recognition applications, for non-contact navigation and gaming in consumer electronics such as smartphones, TV and tablets is one of the key reasons driving the growth of the market. VCSELs have found wide adoption in data communication industry. The rapid increase in demand of low energy optical storage VCSELs with fast switching capabilities in high capacity data centers and servers is propelling the growth of the global market. Additionally, the growing demand of VCSELs in ultrahigh density magnetic storage and industrial heating including commercial print shops and paint curing are further analyzed to bolster the VCSELs market. VCSELs are also used for illumination for IR cameras for safety, security and night vision. Moreover, GaN VCSELs are used in high-density optical storage, displays, printing, and bio-sensing applications.
Some of the key companies operating in the global VCSELs market include Alight Technologies A/S, Avago Technologies, Finisar Corporation, Phillips Photonics, Litrax Technology Co. Ltd., Sumitomo Electric Industries Ltd., PD-LD Inc., OECA Optoelectronics Component and Applications GmbH, and Sacher Lasertechnik GmbH.
