Dr. Bernard Didier F. Casse

Bernard Didier F. Casse, Ph.D. is Lead Research Scientist in experimental nano-optics at the Electronic Materials Research Institute (eMRI) in Northeastern University, Boston MA.
His research thrust includes high-visibility projects such as engineering nanoscale negative-index photonic crystals (or metamaterials) for optical communication, subwavelength resolution imaging, trapping light, and more recently solar energy, as well as micromanufacturing military-significant antennas. His latest work on ultra-short focal length nano-optical microlens for high-pixel count digital imaging, published in Applied Physics Letters, has been featured in Nature and received substantial media coverage. He has recently demonstrated a photonic crystal superlens, in optics, capable of beating the diffraction limit.
In earlier years, at the Singapore Synchrotron Light Source (SSLS), he produced the first full-fledge THz microfabricated metamaterial, and pioneered the fabrication of truly 3D metamaterials and multilayered resonator structures using X-ray lithography. The micro-metamaterials resonators that were manufactured made the cover of the first issue of the Advances in Synchrotron Radiation (asr) Journal. Furthermore he was involved in foundry services, at the light source, and played a key role in successfully delivering several high-tech commercial projects for world-renowned companies and world-class research institutions. He also fabricated the premier proton beam micromachined scaffolds for future tissue engineering applications at the Center for Ion Beam Applications (CIBA) in Singapore.
Didier is an expert in high-end nanolithography and optics. He is a qualified super-user of the Center for Nanoscale Systems (CNS) in Harvard university and the NSF Center for High-rate Nanomanufacturing (CHN). He has the highest level of expertise in nanofabrication in cleanroom environment and mastered an extensive repertoire of advanced optical and metrology equipment including synchrotron radiation beamline optics.
Didier has close to 30 peer-reviewed publications, in the areas of nanotechnology and metamaterials, in high-impact factor journals including Physical Review Letters, Applied Physics Letters, Tissue Engineering, Nuclear Instruments & Methods B, Nanotechnology, and Advances in Synchrotron Radiation. He is also an official ad hoc referee for the reputable journals “Applied Physics Letters”, “Journal of Applied Physics”, and “Physical Review Letters”.
He has close to 15 technical talks in the U.S. and internationally. He recently delivered an invited talk at the SPIE Optics+Photonics (NanoScience+Engineering 2008) in San Diego, CA and was invited earlier to co-chair a session in Nanoscale Electromagnetics/Photonics/Plasmonics at the Progress In Electromagnetics Research Symposium (PIERS 08) in Cambridge, MA. His latest awards include being listed in Marquis Who’s Who in America (2009 Edition); Who’s Who in the World (25th Silver Anniversary Edition 2008), Best Poster Award (MRS FALL Meeting 2007), and Best paper award in Asia-Pacific Conference of Transducers and Micro-Nano Technology (2006).
Didier possesses advanced knowledge of numerical computations, modeling and simulations. He has significant experience in utilizing advanced electromagnetic solvers, Unix-based platforms and other esoteric software. Armed with extensive knowledge of C/Perl/Python, he contributes codes to open source software in his spare time. He also used to maintain a Fedora Linux YUM repository of the enlightenment DR17 desktop shell.
He earned his doctoral degree in Physics (specialized in micro-/nano engineering of metamaterials) in 2007 from the prestigious National University of Singapore, which falls in the same league as the U.S. top universities. He has been a researcher at Northeastern University since October 2006. He is a member of the American Physical Society (APS), the American Association for the Advancement of Science (AAAS), the Materials Research Society (MRS), the National Postdoc Association (NPA), and the High IQ Society.
