Latest Patents

Brand's latest patents include groundbreaking technologies for optical switching. One of his notable inventions is a **high-tolerance broadband-optical switch** in planar lightwave circuits. This innovative switch utilizes adiabatic couplers featuring a pair of asymmetric waveguides with variable curvature sections. The design includes two configurations: a 2×2 arrangement based on a Mach-Zehnder interferometer, which utilizes two adiabatic couplers, and a 1×2 or 2×1 setup that incorporates an adiabatic coupler and Y-splitter. The implementation of these variable curvature adiabatic couplers on a silicon substrate ensures an outstanding broadband range of 1.2-1.7 µm, along with remarkable extinction ratios exceeding 35 dB. These switches are not only compact but also demonstrate low fabrication sensitivity and polarization-independent operation, featuring faster switching times and reduced power consumption.

Another significant patent is a **method and system for obtaining variable optical attenuation** with minimal polarization-dependent loss across an ultra-wide dynamic range. This invention optimizes the operation of a variable optical attenuator within a planar lightwave circuit. By integrating a first Mach-Zehnder interferometer with a second one, Brand's method allows for the required total attenuation while achieving effectively nil polarization-dependent loss.
