Technology Generator

Dr. Caesar SalomaDr. Caesar A. Saloma published his first paper in the February 15, 1990 issue of Optics Letters about his PhD dissertation on speckle reduction in laser microscopy supervised by Osaka University’s Professor Shigeo Minami and Dr Satoshi Kawata. This essentially signaled the start of cutting-edge photonics research at the Instrumentation Physics Laboratory of the National Institute of Physics, University of the Philippines.  Photonics is the science and technology of generating, guiding, and detecting light energy (photons).

Between February 1990 and December 2007, Dr. Saloma’s group at IPL published over 80 papers in leading optics and applied physics journals in the US and Europe including Optics Express, Optics Letters, Applied Physics Letters, and Applied Optics. A number of these publications was featured in technology magazines like Photonics Spectra (August 2002 issue, April 2006 issue), MRS Bulletin (December 2004, Materials Research Society), Laser Focus World (January 2006), GIT Imaging & Microscopy (March 2006), and Optics & Photonics News (December 2006, Optical Society of America). 

On June 26, 2007, the NIP-IPL researchers were awarded a US patent (No. 7,235,988; Inventors: C. Saloma, V. Daria, J. Miranda) for inventing a method to generate high contrast images of semiconductor sites via one-photon optical beam induced current imaging and confocal reflectance microscopy.

Between April 1993 and April 2008, Dr. Saloma mentored 17 PhD graduates in photonics and complex systems research at UP-NIP.  The International Commission for Optics conferred the 2004 Galileo Galilei Award to Dr. Saloma for his significant contributions to optics achieved under less favorable conditions. He is the first and only ASEAN scientist to receive such award.
