A research team led by Professor Youshin No from Department of Physics at Konkuk University recently developed microstructural printing technology using transparent micro-polymer structures, leading its way for ultra-small miners to be individually integrated into high-density optical circuits. The research achievement of Professor has been published in ACS Photonics on December 3rd. (Thesis title: On-Chip Transferrable Microdisk Lasers)
The ultra-fast, ultra-small optical integrated circuit, which is drawing attention as future technology, consists of a variety of individual optical elements. In order to successfully realize this circuit, it is essential to develop technology that integrates the individual elements into the circuit at the exact location.
It was difficult for the existing technologies to separately select, align, and transfer to a desired location as the technologies were focusing on large-area pressing with no high transcription accuracy required. The research team, therefore, developed printing press technology optimized for microstructure pressing by introducing a transparent micro-polymer structure. With the application of the technology, the research team even observed actual laser operation by transferring a few micro-sized ultra-small laser to a desired location with high pressing accuracy.
Professor No said, “This development will be a core technology that can accelerate the actual implementation of future ultra-small optical integrated circuits in the future.”
