Title : Non-invasive infrared diagnoses, via angle-coherent tomographic infrared spectroscopy, realized via 3D photonic quantum ring laser

Abstract:

Non-invasive infrared diagnoses employing 3-dimensional (3D) angle-resolved light cones (ALCs) from 3D photonic quantum ring (PQR) are explained for angle-resolved coherent tomographic infrared spectroscopy (ACTIRS).

Audience Take Away Notes:

• The detailed 3D analysis follows when we understand helical standing wave propagations CW and CCW within a resonant toroidal cavity. The 3D PQR characteristics with ultra-low threshold current, in contrast to the usual 1D/2D lasers, then follow when the recombinant 2D carriers are mostly confined to the 2D quantum well plane which constructs concentric 1D quantum rings of half-wavelength intervals in spontaneous formation within the 2D peripheral Rayleigh active region.
• The key property of the PQR laser is the conformal 3D features while it presents typical radial angle-resolved blue-shifts. These features generate particular inclination angles of 3D PQR laser radiation creating conformal ALCs with distinct path-dependent blue-shifts through the human organs

Biography:

Dr. B. H. Park studied Electronic Engineering at the Gyeongbuk National University, Korea until 1995. He then received his PhD degree in 2002, and M.S. in 1997 at the Pohang University of Science & Technology. He joined Samsung Electronics Co, Ltd., where he has focused on the commercialization of optical devices, such as DFB, EML, and VCSEL as well as blue laser diode and LED. His recent research topic is developing 3D depth sensors for mobile applications. He has published more than over 20 research articles in SCI (E) journals with 100 citations.
