Light that Twists inside fibers

March 11, 2015 @ 4:00 pm - 5:00 pm
Central Lecture Theatre (CLT)

Speaker :- Siddharth Ramachandran Professor, ECE Department & Photonics Center, Boston University, Boston, MA, USA, http://people.bu.edu/sidr Abstract :-In the last decade, some of the most extensively studied complex light beams are optical vortices, which possess phase or polarization singularities. These beams are interesting because they resemble the emission patterns of single molecule dipoles, or because they potentially represent an infinite set of eigenstates that can be constructed with light. Their use has been demonstrated in, or proposed for, several applications…

Heteroepitaxy of InP on Si and Buried Heterostructure Quantum Cascade Lasers

July 17, 2015 @ 3:00 pm - 5:00 pm
ESB 244

Speaker: Prof. Sebastian Lourdudoss, KTH, Sweden Abstract: The seminar consists of two parts. The first part deals with heteroepitaxy of InP on Si. Combination of III-V semiconductor based devices on silicon is advantageous for electronics-photonics integration and cost effective solar cells. So far bonding approaches are predominant. Heteroepitaxial approach is more attractive for large scale integration. I will present our approach and some recent results on near laser emission from quantum wells grown on InP on Si and demonstration of…

Power Electronics in VLSI : Design Challenges and Solutions

August 13, 2015 @ 3:00 pm - 5:00 pm
ESB 244

Speaker : Ignatius Bezzam Abstract : Power  consumption is  a  burning  issue  in  high  performance  systems  based  on  deep submicron  (DSM)  processors  (CPUs  and  GPUs). Resonant circuit operation for power consumption improvements in high speed clocking applications has been extensively studied. The  energy  used  to  charge  the  clock  grid  node  each  period  can  be  recycled  within  the  LC resonant  tank  network  formed  by  the  large  global  clock  capacitance  and  integrated  inductors. Novel integration of resonant circuits that can save several watts of…
