Dr. Khaled Mnaymneh,
Staff Scientist @ The Lurie Nanofabrication Facility,
University of Michigan.


In 1999 researchers convinced light to travel at the speed of a bicycle (Hau 1999).  By electromagnetically inducing transparency in a Bose-Einstein condensate, an optical pulse was slowed to a mere 17 meters per second as it traveled through the condensate.  Although the implications of this experiment are far-reaching, researchers quickly realized that passing light through atom vapors at exotic temperatures was not a very practical route towards real-world applications.  Enter nanostructured materials.  Nanostructured materials, such as photonic crystals, create the conditions for slow light by carefully orchestrating diffraction effects from composite boundary conditions that define the nanostructure.  Done correctly, one has a system of slow moving optical signals whose strong light-matter interactions enable novel functionalities such as on-chip single-photon collection and routing, and small-footprint optical sensors for biosensing and inertial systems.  In this Webinar, using a freely available electromagnetic frequency domain solver software known as MIT MPB, I will demonstrate how to design and locally implement slow light engineering in an on-chip compact optical interferometry architecture.  Excellent agreement between simulation and experiments will be shown and discussed.



Dr. Khaled Mnaymneh is a staff scientist and NNIN outreach coordinator at the Lurie Nanofabrication Facility at the University of Michigan.  After receiving his doctorate degree from Carleton University in Ottawa, Canada in the area of Holographic Lithographic and Photonic Quasicrystals, he spent two years at the University of St. Andrews in Scotland working on integrating InAs/GaAs quantum dots in photonic crystal cavities.  He then returned to Ottawa, Canada as a Research Officer at the National Research Council developing selective epitaxy techniques for scalable quantum information systems such as quantum encryption applications.
