News about Ammono

Since 1984, OPTO Taiwan which is a part of the Photonics Festival 2012 has been the annual event for the photonics industry. The exhibition is the main optoelectronic and photonic meeting point in Asia. Ammono as a substrate maker is at the very beginning of the value chain for those markets and will be exhibiting this year its latest products. Our combined technical/sales team supported by Ammono’s Taiwanese distributor Litrax will exhibit and provide technical and commercial information both in English and in Chinese. Meet us in Taipei at OPTO TAIWAN , June 19-21, 2012 at the TWTC Nangang Exhibition Hall, both # L1102.

As GaN based technologies get more mature Ammono’s customers instead of developing devices themselves from scratch start to have also interest in epitaxial structures on bulk AMMONO-GaN. This saves time necessary to optimize epitaxial technology on Ammono’s innovative substrates. In order to better fit customer expectation Ammono started to cooperate with epi-partners who provide epi-structures on AMMONO-GaN. Different classes of products are possible:

  • high quality epi-ready homoepitaxial GaN templates on GaN (n-type, p-type, semi-insulating GaN),
  • complete epitaxial structures of high brightness light emitting diodes (HB LEDs), lasers and high electron mobility transistors (HEMT),
  • all combinations of InAlGaN structures and devices on bulk GaN.

logo-topganTopGaN, the Polish blue laser maker has just announced a successful demonstration of a novel blue laser architecture based on Ammono’s substrate. An output power of 4W cw was obtained for a blue laser array of 16 stripes. The result is built on two main characteristics of Ammono-GaN. A high carrier concentration of the substrate, which is 1019 cm-3 and a low dislocation density which is 104 cm-2. This result is the best world result today and shows the very high potential of Ammono substrates for pushing the blue laser technology to its further limits.
