Vertical Cavity Surface Emitting Lasers (VCSELs)
An element changing electric signals to optical signals, the VCSEL (Vertical-Cavity Surface-Emitting Laser) is a micro-semiconductor laser that generates laser beams coming out on wafer surface using compound semiconductors. Unlike an edge-emitting laser diode, a VCSEL emits circular laser beams vertically from a substrate surface so that it can be easily connected with a photodetector or an optical fiber. As two-dimensional arrays can be easily performed and executed, parallel signals can be managed and processed. With the downsizing of elements, large scale integration can be achieved. The VCSEL reduces power consumption and is heat-resistant, making its manufacturing process simple. The VCSEL is applied in various fields, including digital media, such as laser printers, laser mouse devices, DVIs, HDMIs, high-speed PCBs and home networks. In the automotive industry, it is applied in multi-media networks and safety sensors. Regarding IT, it is applied to Gigabit Ethernet SAN, SONET and VSR. VCSELs are also applicable in sensors, for encoders and gas sensors. In the medical and bio areas, VCSELs are used for blood glucose meters and lasers for skin care.
Lasermate Group, Inc. maintains close coordination with OEMs to assist in the design with VCSEL components and sub-assemblies to develop new products and to meet customer's needs and expectations. Our VCSELs are the promising emitter for fiber data communication in the speed ranges of 100Mbs and 10Gbs. The VCSELs enable high performance systems in Gigabit Ethernet, Fiber Channel, and ATM markets. Through the integration with original equipment manufacturer's (OEM) systems design, our 850 nm VCSELs provide enhanced performance benefits to a variety of applications, such as local area networks (LAN), telecommunication switches, optical storage and other optoelectronic systems.

Unlike the VCSEL, a photodiode (PD) is a compound semiconductor element that changes optical signals to electric signals. The compound semiconductor-based PD has the ability to receive light as a high-speed communication detector and a highly sensitive sensor because of its unique characteristics that silicone does not possess. A PIN photodiode exhibits almost the same applications as a VCSEL and is applied to areas that include digital media, cars, IT, sensors, medicine and biology.
Lasermate Group, Inc. offers various photodiodes: GaAs photodiodes, InGaAs photodiodes and Silicon photodiodes. Our photodiodes are highly sensitive and reliable for data communication and telecommunication applications. Our photodiodes are available in various package types, including PD chips, TO-can and connectorized LC/FC/SC/ST receptacle and pigtail.

RCLED and LED
Lasermate Group, Inc. offers RCLEDs (Resonant-Cavity Light-Emitting Diodes) and LEDs (Light-Emitting Diodes). RCLED is a light-emitting diode using compound semiconductors. VCSELs, LDs and LEDs are 650nm-band light sources for optical communication used for POF systems. All of them are pn-junction semiconductors. Whereas semiconductor lasers are stimulated emissions, LEDs are spontaneous emissions. Therefore, the wavelength and status of lights are different. In comparison with semiconductor lasers, LEDs have good output power linearity, create little noise, have long durability and are highly reliable and inexpensive, but they are less effective in terms of generating power, the speed of response and coupling efficiency. RCLEDs, however, have resolved the flaws of semiconductor lasers, and light-emitting diodes are gaining in popularity. Surface-emitting RCLEDs are excellent in terms of coupling efficiency, the speed of response, temperature characteristics and durability. RCLEDs are applied to control sensors of cars, car audios, automatic navigation systems, military vehicles, combat planes, airplanes and ships.
