Latest Patents
One of his latest patents is titled "Low noise optical storage system based on an optical polarimetric delay line." This invention describes a system and method that utilizes a multimode diode laser and polarization-maintaining fibers to achieve a high signal-to-noise ratio in magneto-optical storage systems. The system effectively splits an incoming main light signal into two orthogonal polarization states, which then propagate over different distances before recombining. By pulsing the laser at a high frequency and selecting an appropriate path difference for the polarization states, the system successfully eliminates first-order spectral polarization noise that may arise from potential errors in key optical components.
Another significant patent is "Refractive index matching means coupled to an optical fiber for eliminating spurious light." This invention involves an optical data storage system that employs optical fibers for transferring information to and from storage media, specifically magneto-optical storage disks. The use of low-birefringence optical fibers allows for accurate reproduction of the polarization state conveyed by the optical fiber, resulting in reduced noise. Various noise reduction techniques are implemented to minimize or eliminate spurious reflections at the end faces of the optical fiber, enhancing the overall performance of the storage system.
