BERLIN, Germany, March 11, 2013 VI Systems GmbH a leader in optical engines and components and the Technical University of Berlin demonstrated error-free 10 Gbit/s digital signal transmission using a 1310 nm duo-section laser with a monolithic electro-optic-modulator (EOM) section. The device can provide simultaneously high speed active signal transmission and the delivery of high-frequency (40GHz) signal through the mode-locked operation. As the EOM section of the laser has a small surface area and operates under reverse bias, the power consumption of the driver electronics can be greatly reduced. Mode-locking frequencies in the range of 60-80GHz and the corresponding active data transmission at 20 - 25 Gbit/s can be accessible with further optimization. The patent-protected concept of electro-optically modulated pulsed laser for active data transmission can provide multiple advantages in telecommunications and wireless signal distribution, particularly for wireless Gigabit transmission WiGig and existing wireless (Wi-Fi) applications
