About TopGaN

TopGaN, a company founded in 2001, is one of the pioneers in the development of gallium nitride based technologies in Europe.

TopGaN was a second company in Europe to demonstrate violet laser diodes and since then it introduced many innovative technologies in the field of nitride emitters, including:

• Laser diodes structures on “plasmonic” substrates,
• Molecular Beam Epitaxy growth of gallium nitride laser diode structures,
• Multi-Watts laser diode arrays and mini-arrays,
• Demonstration of high power blue-violet superluminescent diodes,
• Multiple wavelengths laser diode arrays.

TopGaN is focusing on close cooperation with its customers to adapt the best its products to the market.
