Latest Patents
Fleming's latest patents include the Magneto-optic bypass switch and the Fiber optic bypass switch. The Magneto-optic bypass switch is designed to receive arbitrarily polarized light from an input optical fiber, which is then divided into P and S-polarized light beams by a polarization beamsplitter. These beams are focused onto a magneto-optic garnet, where the plane of polarization is rotated according to a desired switching function, directing the light to an output optical fiber based on the polarization rotation state established in the garnet. The Fiber optic bypass switch features a variable diffraction element that responds to acoustical signals, allowing it to couple light signals from input ports to output ports based on different diffraction indices. This innovative design enhances the flexibility and efficiency of optical signal routing.
