Latest Patents
Benedick's latest patents include groundbreaking methods for manipulating the optical phase of laser beams. One of his significant inventions involves binary-phase-shift-key, phase-modulated waveforms with gigahertz bandwidths, which are suitable for kilowatt-class fiber amplifiers. This technology allows for the narrowing of the laser's linewidth via second-harmonic, sum-frequency, or difference-frequency generation in a second-order nonlinear crystal. Additionally, he has developed a method where the spectrum of an optical signal phase-modulated with a pseudo-random bit sequence (PRBS) waveform can recover its original optical spectrum when frequency-doubled using second-harmonic generation (SHG). This innovative approach effectively cancels the PRBS waveform, converting the underlying laser spectrum to the second-harmonic wavelength.
Another notable patent addresses stimulated Brillouin scattering (SBS) suppression in coherent beam combining. Benedick's method involves phase-modulating beams with a PRBS to prevent SBS downstream. He introduces a unique approach to achieve true-time-delay by stabilizing the relative phase of PRBS patterns through phase-locking master oscillators. This technique allows for precise compensation of physical path length mismatches in optical fibers, enhancing the efficiency of coherent beam combining.
