At the international scientific workshop iNOW, Prof. Ledenstov, CEO of VI Systems GmbH, revealed the technology advances of the company in the field of ultrahigh-speed components for VCSEL and PIN-based optical links. The nano-optoelectronic workshop iNOW is chaired by the University of California, Berkeley, the Technical University of Berlin, Germany and Royal Institute of Technology, Stockholm, Sweden.
BERLIN, Germany, Aug 12, 2009
VI Systems GmbH, a leader in ultra-high speed optical components for data communication presented at the iNOW workshop the latest achievements in ultrahigh-speed components for fiber-optic links and its proprietary Electro-Optically Modulated Distributed Bragg Reflector (EOM DBR) Vertical Cavity Surface Emitting Laser (VCSEL). Prof. Dr. Ledentsov, CEO of VI Systems GmbH revealed data on high speed optical components: PIN chips with -3dB bandwidth of 30GHz, VCSEL chips with resonance frequency beyond 22GHz. Preliminary information on 35GHz transimpedance amplifier (TIA) and driver chips as well as the flip-chip bonding micromodule bonding approach was provided. Prototype test results for the EOM DBR VCSEL which operates at a constant current density while the amplitude modulation is achieved by changing DBR reflectance via a very low voltage change are provided. High output power up to 85oC (2-15 mW, depending on the aperture size) high extinction ratio (up to 5dB) and open eye data transmission are demonstrated.
The goal is to manufacturer optical components which will allow serial data rates of up to 40/100 Gbit/s for short reach multi mode optical fiber links and chip-to-chip optical interconnects. A dramatic reduction in power consumption in data centers is possible by implementing these low power optical components and modules.
The iNOW 2009 workshop engages participants in considerations of state-of-the-art nanoscale semiconductor processing and synthesis, the new physics of tailoring material’s optical and electrical properties, new advances in characterization techniques, and new devices with novel functionalities. The venue is chaired by the University of California, Berkeley, the Technical University of Berlin, Germany and Royal Institute of Technology, Stockholm, Sweden.
