A physics professor at the nation's most renowned research university has developed a nano-sized semiconductor laser, the Korea Advanced Institute of Science and Technology (KAIST) said Thursday.
KAIST professor Cho Yong-hoon and his research team recently succeeded in converging photonic crystal particles with paper, the university said. The achievement is expected to be widely applied to developing sensors for medical purposes, as paper is highly absorbent and the particles are notable for their extreme sensitivity, KAIST explained.
The team replaced traditional semiconductor boards with paper, which can drastically cut costs in mass-producing the laser. Paper is also better for the environment than any other materials when destroying the laser, said the team.
"Our technology helps contribute to creating eco-friendly particles platforms as it is a combination of paper and crystal particles," Cho said in a statement. "By converging cheap paper and high-performance photonic crystal sensors, expectations are that the technology can be more widely used to develop other related areas due to its price-competitiveness."
As shown in pregnancy test kits, which have been commercialized, paper has relatively high water absorbency, said the research team. This is why the recent achievement can be used to develop a variety of small sensors for diagnosis in other physical examinations, it added.
