Space-time refraction of space-time wave packets
Zeki Hayran, John B. Pendry
Space-time modulation of refractive index can produce synthetically moving interfaces with arbitrary apparent velocities, including superluminal motion, offering new ways to contro…
Chirality-driven all-optical image differentiation
Stefanos Fr. Koufidis, Zeki Hayran, Francesco Monticone +2
Optical analog computing enables powerful functionalities, including spatial differentiation, image processing, and ultrafast linear operations. Yet, most existing approaches rely…
Broadband Low-loss Unidirectional Reflection On-chip with Asymmetric Dielectric Metasurface
Heijun Jeong, Zeki Hayran, Yuan Liu +6
Metasurface has emerged as a powerful platform for controlling light at subwavelength thickness, enabling new functionalities for imaging, polarization manipulation, and angular mo…
