Latest Patents

Among her noteworthy patents is "Active control and detection of two nearly orthogonal polarizations in a fiber for heterodyne interferometry." This patent describes a sophisticated polarization control system that comprises a light source generating two beams with varying polarization states and optical frequencies. The system utilizes a polarization state modulator to adjust the polarization states of these beams. The configuration includes two detector paths, each generating beat signals after passing through orthogonal polarizers, leading to an amplitude detector that functions to refine the modulation of the polarization states.

Another of her recent innovations, titled "Polarization controller using spatial filtering," focuses on improving the polarization extinction ratio. In this invention, the polarization state of a light beam is altered, introducing spatially non-uniform polarization states. The innovation involves spatially filtering these states either through polarization-maintaining single-mode fibers or through apertures that refine the beam's amplitude.
