Broadband generation of quasi bound-state-in-continuum modes using subwavelength truncated cone resonators
Chun-Ho Lee, Mohamad Reza Nurrahman, Dongha Kim +3
Allowing a high quality factor (Q-factor) to a sub-wavelength dielectric resonator, quasi-bound states in the continuum (Q-BIC) has gained much interest. However, the Q-BIC resonan…
Spontaneous generation and active manipulation of real-space optical vortex
Dongha Kim, Arthur Baucour, Yun-Seok Choi +2
Optical vortices host the orbital nature of photons, which offers an extra degree of freedom in photonic applications. Unlike vortices in other physical entities, optical vortices…
Plasmonic photonic crystal mirror for long-lived interlayer exciton generation
Sanghyeok Park, Dongha Kim, Min-Kyo Seo
Interlayer excitons in van der Waals heterostructures of two-dimensional transition metal dichalcogenides have recently emerged as a fascinating platform for quantum many-body effe…
Perfect optical absorption-enhanced magneto-optic Kerr effect microscopy
Dongha Kim, Young-Wan Oh, Jong-Uk Kim +4
Magnetic and spintronic media have offered fundamental scientific subjects and technological applications. Magneto-optic Kerr effect (MOKE) microscopy provides the most accessible…
