Bahram Jalali

from Wikipedia, the free encyclopedia

Bahram Jalali is an American applied physicist and optics engineer.

Jalali received his PhD in Applied Physics from Columbia University in 1989 and then worked at Bell Laboratories in Murray Hill before moving to the University of California, Los Angeles (UCLA) in 2002 . There he is Northrop-Grumman Optoelectronics Chair Professor of Electrical Engineering and Head of Physical Wave Electronics . He is also on the Biomedical Engineering and Surgery Schools of the UCLA School of Medicine and the California NanoSystems Institute (CNSI).

From 2001 to 2004 he advised Intel .

Jalali specializes in silicon and microwave photonics, instrument building for big data processing , analog-to-digital conversion, biomedical diagnostics and statistics on rare events. He has published over 300 scientific papers and holds 9 patents (as of 2013).

He demonstrated with his post-doctoral Ozdal Boyraz the first silicon - the semiconductor laser using Raman scattering . The first semiconductor lasers used other semiconductors such as gallium arsenide ( III-V compound semiconductor ), since silicon is a semiconductor with an indirect band gap (electron-hole combination only works through interaction with a phonon). On the other hand, silicon is one of the best known and technologically best mastered semiconductor materials.

In biomedical technology he used data analysis methods (STEAM, FIRE for fluorescence samples ) with high data throughput of optical communication technology (e.g. multiplex methods such as WDM), which enables the relatively error-free identification of abnormal cancer cells in blood samples for early detection. New image transformation processes were developed (anamorphic stretch transform).

In 2007 he demonstrated with Daniel Solli (UCLA), Claus Ropers (Max Born Institute Berlin) and other monster waves (Freak Waves) in light guides, i.e. transition into the supercontinuum even with relatively low optical excitation due to nonlinear effects. Until then, this wave phenomenon was mainly known from hydrodynamics and shipping.

In 2007 he received the RW Wood Prize and in 2012 the Aron Kressel Award of the IEEE Photonics Society, both for contributions to silicon photonics. He is a Fellow of the Optical Society of America (2004), the IEEE, and the American Physical Society (2011). In 2005 he was voted into the Scientific American Top 50.
