Albis Optoelectronics is a leading designer, developer and manufacturer of high-speed photodiodes. Since 20 years the company offers a diversified product portfolio consisting of InP and GaAs based PIN photodiodes, APDs and high-speed detector modules up to 60 GHz.
The fabrication facilities based in Rueschlikon (Zurich) offer full in-house production from front-end to back-end and include a class 100 clean room and extensive test and qualification laboratories. New products for emerging markets as well as customer specific modifications are developed by a team of experienced scientists and engineers. The company focuses on high reliable and high quality products fulfilling Telcordia GR-468 and MIL-STD-883E requirements.

Full In-House Production and Testing

In 2001 the fabrication facility started mass-production and has produced millions of photodiodes since. Chip design, manufacturing and testing is all done in-house thus ensuring a constant high level of product quality.

One of the biggest challenges facing today’s optical networks is guaranteeing 99.999% availability at an affordable cost. This challenge can only be met by applying stringent quality criteria starting at bare chip level in order to avoid failure of higher level, more costly modules. For our photodiodes this means that they undergo a rigorous testing program including:

  • 100% on wafer dark current measurements
  • 100% on wafer forward current measurements
  • 100% on wafer capacitance measurements

In addition, a 100% visual inspection following MIL-STD-883E is carried out as well as responsivity and bond pull testing on a sample basis for each processed wafer.

Telcordia GR-468 Qualification

After passing all the previous testing stages, a photodiode is likely to have a long lifetime without any performance degradation. This is confirmed in our reliability laboratory where lifetime is tested under stressed conditions such as high temperature and high humidity. Reliability testing was started back in 1997 and since then more than 120 billion normalized device hours were accumulated. This vast amount of data is analyzed in detail in our extensive reliability reports that have satisfied the demands of the most quality conscious Tier 1 customers in our industry.

ISO 9001:2008 Certified

As a result of the continuous quality efforts, Albis Optoelectronics successfully obtained the ISO 9001:2008 certification in 2004 for its complete operations including product development, production and sales. The certificate ensures that all company processes are well defined and consistently tracked. In addition, interaction with customers worldwide is facilitated and a company atmosphere focusing on continuous process and quality improvements is guaranteed.
