Syllabus 2013

Course Overview            

In addition to four-credit hour OPT 253/OPT 453/PHY 434 course we have adapted to the main challenge (the lack of space in the curriculum) by developing a series of modular 3-hour experiments and 20-min-demonstrations that were incorporated into a number of courses ranging from freshman (OPT 101) to senior level, in both physics (PHY 243 W) and engineering (OPT 223). Rochester Monroe Community College students also benefited from this facility by carrying out two 3-hour labs at the University of Rochester (see 2012,2011,2010,2009, 2008 years and Freshman Research Projects).

Experiments:

Lab 1 - Entanglement and Bell's Inequalities (Wilmot 405 & 323) Manual (PDF) Lecture (PDF) Lecture 2 (PPT)
Entanglement is the most exciting and mysterious property of some quantum mechanical systems when property of one particle correlated with the property of the other. It does not matter how far apart such entangled particles are located. Among the best known applications of entanglement are quantum communication and quantum state teleportation. In this lab students obtain a polarization entangled state of two photons using spontaneous parametric down conversion in two type I BBO crystals. Bell’s inequality [see paper J. Eberly, Amer. J. Phys., 70 (3), 276 (2002)] is a classical relation and in quantum mechanics it is violated. To calculate Bell’s inequality students use measurements of the coincidence counts between two single-photon detectors at different settings of linear polarizers in front of each detector. These are located in the opposite sides of a cone of down converted light. Initially this experiment was described in paper P.G. Kwiat et. al., Phys. Rev. A. 60, R773 (1999). For undergraduate laboratory the experiment was developed in papers D. Dehlinger and M.W. Mitchell, Am. J. Phys, 70, 898 (2002) and D. Dehlinger and M.W. Mitchell, Am. J. Phys, 70, 903 (2002).                

Lab 2 - Single-Photon Interference (Wilmot 406) Manual (PDF) Lecture on EM-CCD camera (PPT)
Single-photon Young’s double slit experiment shows wave-particle duality. Measurements are made with laser beam attenuated to a single photon level. Using electron multiplied, cooled CCD camera we can observe both particle behavior of photons (separate bright pixels) at short exposure times and wave behavior (interference fringes) at longer exposure times. Random bright pixels (particle behavior) appear in the areas of maxima of the interference fringes (wave behavior). Mach-Zehnder interferometer is used for the demonstration of single-photon interference after removing “which-way” information (identification of the path). See also undergraduate experiment by M.B. Schneider and I.A. LaPuma, Am. J. Phys., 70 (3), 266-271 (2002).

Lab 3 - Confocal Microscope Imaging of Single-Emitter Fluorescence (Wilmot 323) Manual (PDF) Lecture 1 (PDF) Lecture 2 (PDF)
In this lab students learn how to produce single photons obeying the laws of quantum mechanics. A single-photon source (SPS) that efficiently produces photons exhibited antibunching is a pivotal hardware element in photonic quantum information technology. Secure quantum communication (see attached paper) with single photons will prevent any potential eavesdropper from intercepting the message without the receiver's noticing. SPS also enables quantum computation using linear optical elements and photodetectors. To produce single photons exhibiting antibunching a laser beam should be focused into area containing only one emitter. A single emitter emits single photon at a time because of fluorescent lifetime. In this lab students get acquainted with a confocal fluorescence microscopy of single emitters and photonic bandgap materials. Using confocal microscope they image the fluorescence of single colloidal semiconductor quantum dots and single dye molecules. Students also prepare 1-D photonic bandgap chiral liquid crystal samples doped with quantum dots and obtain images of quantum dots in this photonic bandgap structure.

Lab 4 - Hanbury Brown & Twiss Setup, Photon Antibunching (Wilmot 323) Manual (PDF) Thesis on Single-Photon Source (PDF)
In this lab students learn how to prove that a source of light is a single photon source. In difference with light attenuated to a single photon level, photons from single emitters exhibit antibunching. Students observe fluorescence antibunching from single quantum dots in photonic bandgap liquid crystal host using a Hanbury Brown and Twiss interferometer and measuring time intervals between two consecutive photons using time correlated single photon counting card TimeHarp 200. They also measure fluorescence lifetime of dye molecules.
