'''[{UP}Announcements/UCDavis_DeviceIntegration_Position_2009.pdf|Research Positions in Photonic Electronic Integrated Systems]'''

The Next Generation Networking Systems Laboratory at UC Davis invites applications for Postdoctoral Research Scientists specializing in integrated photonic systems.

The emphasis will be on highly functional computing, communications, and signal processing systems realized by integration of a large number of photonic and electronic components including lasers, modulators, detectors, multiplexers, demultiplexers, optical amplifiers, logic gates, transimpedance amplifiers, and electronic drivers. Such components may be based on semiconductor quantum wells, quantum dots, quantum wires, photonic crystals, plasmonic waveguides, arrayed-waveguide-gratings, mode-locked lasers, wavelength converters, and photonic switches realized on silicon substrate platforms. CMOS compatible fabrication processes will be primarily investigated with additional modifications to allow hetero-integration of InP, GaAs, and other material systems.

Excellent fabrication skills, fine understanding of device physics, and good communication skills are desired.

    '''$9.5 Million Grant for Ultrafast Optical Communications:'''

    The Defense Advanced Research Projects Agency (DARPA) has awarded $9.5 million over three and a half years to UC Davis, MIT and commercial partners to develop new high-speed devices for ultrafast optical communications, imaging and other applications.

    "We will be prototyping a compact, optical arbitrary waveform generator capable of communicating at unprecedented bandwidth, potentially 10 thousand times faster than the fastest commercial communications system today," said co-principal investigator S.J. Ben Yoo, professor of electrical and computer engineering and director of the UC Davis Center for Information Technology Research in the Interests of Society.

    Optical and radio communications devices generate a carrier wave of a specific frequency, for example the transmission frequency of a radio station. The amount of information, or bandwidth, carried by the wave can only be a fraction of that frequency. Optical communications links can carry far more information than radio because light waves have a much higher frequency than radio waves. The DARPA project aims to investigate how to use and manipulate the high carrier frequencies of mid-infrared light most effectively, Yoo said.

    Yoo's research group will use technology invented at UC Davis to design, build and test thumbnail-sized chips that can potentially encode data at rates up to 100 terahertz, 10 thousand times faster than devices currently available. The MIT group, led by Professor Erich Ippen, will build devices to generate the high-frequency carrier wave.

    Apart from high-speed communications, the technology could also be applied for light-based radar devices or "ladar," capable of very high resolution scanning; medical imaging; or in devices for synthesizing very rich electronic tones, Yoo said.

    The other UC Davis investigators in the project are Jonathan Heritage, Anh-Vu Pham, and Brian Kolner, all professors in the Department of Electrical and Computer Engineering. The commercial partners are Inphi Inc. of Westlake Village, Calif., and Multiplex Inc. and Inplane Photonics Inc., both of South Plainfield, N.J.

    The new project, which will fund an additional 15 researchers at UC Davis and others at the industrial partners, grew out of another DARPA-funded project on optical communications technology awarded to Yoo and collaborators in 2002.

    Micro-Optical Device & Systems Positions available in
    Optical Switching, Passive Waveguides, and Laser Designs
    Advanced Integration and Fabrication Techniques
 
    The Optical Switching and Communications Systems group at UC Davis invites applications for PostDoctoral Fellows or Research Scientists specializing in Micro-Optical Communications Systems development. Multiple positions are open and will cover the following areas: 

* Active and Passive Device Design will investigate advanced lasers, optical switches, wavelength converters, high-speed electronics, passive waveguides, and couplers for implementing integrated optical systems.
* Advanced Integration and Fabrication Techniques will investigate advanced fabrication technologies in conjunction with MOCVD regrowth to implement integrated optical systems containing passive and active components.

    The above efforts will closely link with the research activities of the Optical Switching and Communications Systems group and its collaborators including Lawrence Livermore National Laboratory. The group has successfully prototyped optical packet routing systems and will be investigating new integrated systems. The research activities of the group can be found on the [http://sierra.ece.ucdavis.edu|web site].
