“Creation of peculiar beams by photonic-crystal lasers”
It would be no exaggeration to say that “Light” and lasers have supported the recent progress of information technology and nano-technology since the second half of the 20th century. One example to say that the Information storage media such as CDs and DVDs, which are one familiar example, write and read data with lenses and lasers. The fabrication of nano-scaled semi-conductor devices that are a determining factor of computer performance is carried out using the optical technology of photo-lithography. Furthermore, lasers are also being used more widely in the fields of advanced sensing such as bio-sensors and vehicle-mounted sensors. Bio-sensors use laser beams to detect information from fluorescence or the scattering of tiny materials like protein. Meanwhile, vehicle-mounted sensors similarly use laser beams to detect obstacles in front of a car and to inform the driver. Today, these fields require higher-density, higher-precision, higher-sensitivity and higher-speed lasers. I am aspiring to contribute to such fields by developing new laser sources.
In my lecture, I will discuss how to create smaller focal spot, which can lead to the further development of higher density optical data storage, higher accuracy laser processing and higher sensitivity bio-sensing. I will also introduce the development of novel laser sources to produce controlled shapes and polarizations, which can generate smaller focal spot.
