Latest Patents

One of his latest patents is titled "Broadband light funneling in ultrasubwavelength channels having periodic connected unfilled apertures." This invention features a structure designed for broadband light funneling, which includes a two-dimensional periodic array of connected ultrasubwavelength apertures. Each aperture consists of a large sub-aperture that aids in coupling incoming light and a small sub-aperture that funnels a significant fraction of the incident light power. This structure operates nonresonantly and demonstrates efficient ultrabroadband funneling of optical power confined in a remarkably small area, showcasing functional possibilities beyond traditional resonant platforms.

Another notable patent is the "Multicolor photonic crystal laser array." This invention comprises pixels of monolithically grown gain sections, each with a different emission center wavelength. The fabrication of two-dimensional surface-emitting photonic crystal lasers was achieved using a novel top-down nanowire fabrication method. This approach allows for single-mode lasing in the blue-violet spectral region with a tuning range of 60 nm, which is determined purely by the photonic crystal geometry. The potential of this technology can be extended to cover the entire visible spectrum.
