Latest Patents

Among his latest innovations, Haitz has developed a series of light-emitting devices that provide asymmetrical propagation of light. These devices employ solid-state light sources, such as light-emitting diodes (LEDs), and incorporate a unique combination of scattering and extractor elements. The design includes a scattering element with elastic and/or inelastic scattering centers, strategically spaced from the light source element. The asymmetric optical interfaces on opposite sides of the scattering element enable a larger refractive index mismatch towards the light-emitting element. This structure optimizes forward scattering of light while minimizing backscattering towards the light source. The extractor element further enhances efficiency by reducing light reflection at the interface with the surrounding environment.
