Title: Innovations of Janet L Brooks
Introduction
Janet L Brooks is a prominent inventor based in Stanford, CA (US). She has made significant contributions to the field of fiber optics, holding a total of 8 patents. Her work focuses on advanced technologies that enhance the functionality of fiber optic systems.
Latest Patents
Among her latest patents is the "Birefringent fiber narrowband polarization coupler and method of." This invention discloses a fiber optic directional coupler designed for coupling light between two polarization modes. A highly birefringent fiber optic waveguide is positioned on a flat polished surface, with the principal axes of birefringence oriented at an angle, preferably 45 degrees, to the vertical. A ridged block is pressed down on the fiber, with the ridges having longitudinal axes that are transverse to the fiber's longitudinal axis. The stressed regions caused by the ridges facilitate the coupling of light traveling in one polarization mode into another by shifting the axes of birefringence at the boundaries of the stressed regions.
Another notable patent is the "Single mode fiber optic single sideband modulator and method." This invention involves a fiber optic frequency shifter comprising two waveguides with different indices of refraction. In some embodiments, the waveguides represent two modes of propagation within a single fiber. Plural distributed coupling ridges or electrodes are mounted adjacent to piezoelectric materials and are independently driven to apply sinusoidally varying forces to the fiber. This innovative approach allows for the shifting of the input carrier light's frequency by the frequency of the acoustic wave.
