| Abstract | Tiffany Ko, an Electrical Engineering undergraduate student at Princeton University traveled to the host institution Scuola Normale Superiore in Pisa, Italy. During her three month visit, she investigated various THz optoelectronic materials and device. She gained in-depth experience with new experimental equipment and techniques, greatly applicable to future work. Her visit was also very regionally and culturally educational. Without any previous exposure to European culture, Ko gained a new international perspective. As an Asian-American female, she added diversity to both the Italian community and predominantly male workplace. Consequently, she was also able to both share and learn from her colleagues in several aspects. In sum, the international travel was a rich educational experience that fostered strong international relationships and additional future collaborations. |

| Bio | Tiffany Ko is an undergraduate in her junior year currently pursuing a Bachelor's degree in Electrical Engineering and two certificates in Engineering Biology and Materials Science at Princeton University located in Princeton, New Jersey. Previous research focuses include high performance quantum cascade laser design and optimization of QC laser operation for quartz-enhanced photoacoustic spectroscopy (QEPAS). She is currently investigating different fabrication techniques for DFB-QC lasers in the Mid-Infrared Photonics Group located at Princeton University. She is a student member of the IEEE, President of the Princeton University IEEE Student Chapter, and an Education Outreach officer of the Student Leadership Council of MIRTHE. Richard Green received his PhD from the University of Sheffield, for experimental studies of the structural and optical properties of mid-infrared QCLs, and time-resolved intersubband spectroscopy of self-assembled quantum dots. Since 2004 he has worked at the Scuola Normale Superiore, Pisa, Italy. His current research interests include the 6 design and fabrication of terahertz QCLs, and studies of their dynamic properties. David Barate received his PhD in 2005 from the University of Montpellier. Currently he is a Postdoctoral fellow at the National Enterprise for nanoScience and nanotechnology (NEST) research facility located in Scuola Normale Superiore in Pisa, Italy. He has extensive experience and training using molecular beam epitaxy, specializing in antimonide and arsenide materials growth. His current research interests include intersubband physics and devices, quantum cascade lasers, epitaxial growth. Ji-hua Xu is a scientist at the National Enterprise for nanoScience and nanotechnology (NEST) research facility located in Scuola Normale Superiore in Pisa, Italy. Aji Annapara is a doctorate student of the Scuola Normale Superiore. His current research interest include intersubband microcavity polariton dynamics. Alessandro Tredicucci was born in Chiavari, Italy, on January 3, 1968. He received the Ph.D. degree (summa cum laude) in physics from the Scuola Normale Superiore of Pisa in 1997. In 1997 he joined Bell Laboratories, Lucent Technologies, Murray Hill, NJ, in the Semiconductor Physics Research department, where he worked on the development of novel quantum cascade lasers with superlattice active regions. In November 2000 he came back to the Scuola Normale Superiore of Pisa first as assistant professor and, from March 2003, as senior scientist of the INFM (Istitito Nazionale per la Fisica della Materia), now part of CNR. His activity is now mainly concerned with intersubband devices, particularly for the generation and detection of THz radiation and the investigation of new regimes of light-matter interaction. Alessandro Tredicucci has co-authored about 110 journal papers (with over 2100 citations), has given more than 50 invited talks at international conferences, and holds 15 patents. He was the recipient of the 1999 Gilberto Bernardini award and of the 2003 S. Panizza award for opto-electronics of the Italian Physical Society. He was the recipient of the 2005 S. Campisano prize for condensed matter physics of the CNR and of the 2007 Copernico prize for physics. |
