Sun 27Apr2014 11:16AM

Final Exam is set on 5/5 Monday evening 7-9pm in PHYS 201. 

It's a close book exam.  Problems will be similar to HWK problems. You are allowed to bring a self-made equation sheet (A4 paper or smaller), and calculator is allowed.  


Special Seminar on quantum nanophotonics for Monday 4/14 class

Tue 15Apr2014 11:38PM

Instead of regular lecture, for Monday 4/14 class please attend the  

Quantum Photonics Seminar by Prof. Ken Chih-Kang Shih UT Austin), 04/21 Monday, BRK 1001, 9:30am
"Active nanophotonics: from coherent control of quantum emitters to plasmonic nanolasers"

Abstract: 
Light-matter interaction at nanometer scale is emerging as one of the most exciting fields in nanoscience. In combination with the advanced materials synthesis technique to tailor novel low-dimensional electronic systems, new doors are open toward design and realization of nanophotonic devices with novel functionalities. Here I will present two areas that have been pursued in my research group. The first concerns optical coherent control of semiconductor quantum dots as quantum light sources for quantum information applications[1-3]. In particular, I will discuss resonant excitation of quantum emitters in a cavity which enables observation of key signatures of resonant fluorescence such as Mollow triplets and Rabi oscillations in second order photon correlations. The second topic deals with recent exciting development in metal based plasmonic platform which enables the realization of plasmonic nanolasers that break the diffraction limit[4]. I will discuss the first CW operation of plasmonic nanolaser with ultra-low thresholds and show that the underlying mechanism is spasing. I will also show some recent breakthough in achieving full color nanolasers on the same materials platform [5]. Future perspectives of on-chip nanoscale quantum-photonic circuits will be discussed.

Special seminar on NV center in BRK for Monday 2/24 class

Fri 21Feb2014 3:51PM

For the coming Monday 2/24 class, we will not have regular lecture in PHYS, instead it will be replaced by special seminar on diamond NV centers by Chinmay Belthangady in BRK 1001 (starting from 9:30am). Details see http://www.purdue.edu/discoverypark/nanotechnology/events/view.php?id=1530

  

 

This is will be a useful introduction to the physics and an important application of NV center.
