Fraunhofer's HHI orders Aixtron MOCVD tool for InP photonics

31 MARCH 2009 -- Heinrich-Hertz-Institut will upgrade its Photonic Components' department capabilities with the AIX 2600G3 IC MOCVD system.

31 MARCH 2009 -- Aixtron AG (search Lightwave for Aixtron) has announced that in the fourth quarter the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institut (HHI; search Lightwave for HHI), Berlin, Germany, ordered one AIX 2600G3 IC metal-organic chemical vapour deposition (MOCVD) system for the multiwafer growth of indium phosphide (InP)-based optoelectronic devices. The MOCVD tool will be delivered in an 8x4-in. wafer configuration and be shipped in the third quarter of 2009. The institute says this tool will be an essential contribution to further developing the capabilities of its Photonic Components department.

Norbert Grote, department head of Photonic Components, says, "The strong growth of phase-dependent information transmission, together with the demand for WDM optochip solutions at reasonable costs, creates a huge need for photonic integrated circuits. We believe that soon more than 50% of HHI's wafer area will be some kind of integrated solution. We are confident that the ordered AIX 2600G3 IC system will upgrade our MOCVD capabilities to a level sufficient for many years to come."

Harald Kuenzel, leader of HHI's epitaxy group, comments, "We have been doing InP photonics development for more than two decades. Our primary research tools have been the AIX 200 and AIX 200/4 horizontal MOVPE reactors which so far have fulfilled our requirements. Now our program has reached the point where we need to expand our epi capacity and upgrade to the latest technology in terms of area uniformity and multiwafer capability. Our industrial customers are more and more keen on seeing R&D device developments to be compliant with state-of-the art production tools. After reviewing all available options we will once again acquire the best MOCVD tool suited for our needs from Aixtron. It has been our experience that these systems provide excellent reproducibility and uniformity plus a flexibility of configuration that will allow us to rapidly achieve high device quality."

At HHI, research on photonic components covers both telecom and datacom applications and optical sensors and instrumentation, e.g., for medical and environmental monitoring. This involves MOCVD growth of laser diode, detector, and modulator structures in the 1,200-to-1,900 nm spectral range. The new Aixtron reactor will be used for bulk InGaAsP-, QW InGaAsP-, QW InGaAlAs-, and self-assembled InAs quantum-dot-based structures.
