“Lasers & Holography”Invited Talk by Frank DeFreitas

• Three chapter members volunteered at COT OPTO Camp, which had 12 middle-school participants

• “Lasers and Holography” by Frank DeFreitas was sponsored by COT OPTO Camp and our Chapter.

• SPIE CD and posters were handed out

• Students handled hands-on holographic medium

• Students looked through a laser illuminated phase plate to see a rare 3D image of a scientist in his lab

Speaker Bio : Mr. DeFreitas, credited as one of the pioneers of using laser pointers to make holograms, has contributed to several educational programs throughout the country. He is an author to “Shoebox Holography”and director of holoworld.com. His Allentown Holographic studio is featured on SPIE’s CD of “Optics at Work”.

COT OPTO Camp : The Center for Optical Technologies (COT) sponsors a camp experience focusing on Optical Technologies for middle school students. The camp features a demonstration and project based exploration about sound, color, imaging and optical communication.

Talk Abstract : The talk was an overview recent progress made towards harnessing nonlinearities in semiconductors. Recent measurements of the third order nonlinearities in GaAs/AlAs short superlattice structures will be presented. Opportunities and limitations of these structures were discussed. Also two routes to phase matching second order nonlinearities were discussed. The first is through quasi-phase matching achieved via domain disordering in GaAs/AlAs short superlatticestructures. The second is exact phase matching using Bragg reflection waveguides. Routes towards monolithic current injection optical parametric oscillators will be examined in light of the recent experimental results obtained for these Bragg reflection waveguides. Also properties which enable efficient current injection correlated photon pair sources will be discussed.

Speaker Biography : Professor Amr S. Helmy joined the department of Electrical and Computer engineering of the University of Toronto with a mixed experience in academic as well as industrial environments. He received a degree in Electronics and Telecom. from Cairo University in 1993. Both my M.Sc. (9/1995) and Ph.D. (11/1998) degrees were obtained from the University of Glasgow, Scotland, in the field of photonics. The speaker joined Agilent Technologies between 2000 and 2004 where he was involved in developing different Photonic devices ranging form high reliability high power submarine-class 980 nm lasers, to DFBs for un-cooled high temperature operation, to integrated laser/ modulator/amplifier devices. His Research Interests include; Photonic device physics and characterization techniques, non-linear optics in III-V semiconductors, applied optical spectroscopy for III-V optoelectronic devices and materials, III-V fabrication and monolithic integration techniques.

• Invited Talk by Dr. Greg H. Olsen, Entrepreneur, Pioneer Researcher & Space Scientist• Sponsored by NSBE and our chapter

Talk Abstract : Greg Olsen recounted his experience of becoming the third private citizen to orbit the earth on the International Space Station. After training for five months (900 hours) at the Yuri Gagarin Cosmonaut Training Center in Moscow, he launched on a Russian Soyuz rocket TMA-7 on October 1, 2005 with Cosmonaut Valeri Tokarev and Astronaut Bill McArthur (Expedition 12). He then docked to the ISS on October 3, and returned to earth on Soyuz TMA-6 on October 11 with Cosmonaut Sergei Krikalev and Astronaut John Phillips (Expedition 11). He performed more than 150 orbits of the earth and logged almost 4 million miles of weightless travel during his 10 days in space.

“My Space Voyage”, by Dr. Greg OlsenAudience : 65 people from Lehigh, HR, Engineering, Physics, Northampton Community College, the College of New Jersey, faculty, undergrads, grads and local cub scouts group

Post Talk : A tour of the Professor Ooi’s III-V Photonics lab was given to the local cub scouts group.

News Coverage : Lehigh University Press, Lehigh’s “Brown & White”, and Service Electric News Channel

Speaker Bio : Currently, Dr. Olsen is the president of GHO Ventures in Princeton, NJ where he manages his “angel” investments and performs numerous speaking engagements to encourage children – especially minorities and females - to consider careers in science and engineering. He received a BS Physics (1966), a BSEE and MS Physics (1968) from Fairleigh Dickinson University, then was awarded a Ph.D. in Materials Science from the University of Virginia (1971). He was awarded 12 patents, wrote more than 100 technical papers, co-authored several book chapters and has given numerous invited lectures. Dr. Olsen founded two major optics companies which sold for hundreds of millions of dollars and are now owned by two different Fortune 500 companies.

The field of nanoscale photonics has experienced significant growth in the past decade. In this talk, Prof. Ho gave an introduction to some basic interests in semiconductor nanophotonic devices. I will describe how the use of high-refractive-index structures has led to significantly smaller optical waveguides and microscopic optical cavities. These nanoscalephotonic structures open up various possibilities for novel photonic devices. The use of nano optical structures enables the control of atomic emissions that has been used to realize microcavity lasers with very low lasing thresholds and controlled photon statistics. I will describe some of our experimental works, including photonic-wire nanolasers, quantum-dot microdisk lasers, and random lasers. Nanophotonic structures also enable much smaller device sizes and higher integration density, leading to high-density optoelectronic integrated circuits that may be useful for broadband data interconnects on chip. Device and integration examples include photonic crystal lasers, coupled optical resonator devices, and devices with high nonlinear optical interactions. Lastly, I will describe our formulation of a general computational model of complex material media for spatial-temporal electrodynamics simulation using the Finite-Difference Time-Domain (FDTD) method. I will illustrate successful electromagnetic simulation of current-injection photonic-crystal laser, microcavitydisk lasers, and ultrafast all-optical photonic transistors using this simulator.

Event was co-sponsored by Lehigh’s Electrical and Computer Engineering Seminar Series

Biography of the speaker:Dr. Seng-Tiong Ho obtained his Ph.D. in Electrical Engineering from the Massachusetts Institute of Technology in 1989. He also obtained M.S. and B.S. in Electrical Engineering and Computer Science, and B.S. in Physics, all from MIT around 1984. He has been with Northwestern since 1991 and is currently a Professor of Electrical Engineering and Computer Science and the Director of Nanophotonics and Quantum Electronics Research Lab.

Optics Demo Stations

Laser Manipulation :

Using a beam splitter, mirrors, fiber and a grating, students manipulated light from a laser pointer. Laser applications were discussed.

Light Polarization :

Using a polarizer film, students can see the effects of light going through birefringent material such as a plastic cup. As the cup is bent, colorful patterns change according to the stress induced. Students used polarizing filters and splitters (i.e. calcite crystals) to show double images of objects to appear and disappear.

Red-Green-Blue Color Sensor :

Using an RGB connected to a laptop, students measured the color composition of various objects: such as paint swatches, colored gels, M&Ms, Skittles, their hands. of similar tints of color.

Meter Stick Optics :

Students used a meter stick with mounted lenses, objects printed on transparencies and a bulb image to produce a magnified / miniaturized and inverted images of the objects depending on the relative distances between optical components.
