Latest Patents

Sadowski's latest patents include the "Stable Nonlinear Mach-Zehnder Fiber Switch" and the "Nonlinear Optical Coupler Using a Doped Optical Waveguide." The Mach-Zehnder fiber switch is designed to be thermally stable, minimizing temperature gradients that can lead to instability. This compact switch, measuring less than 2 cm between couplers, utilizes heavy doping in one or both arms to create a highly nonlinear region, allowing for effective control of output coupling ratios with low pump powers. The nonlinear optical coupler employs an Erbium-doped optical waveguide, where an optical signal propagates in two spatial modes. A perturbational light signal is used to alter the effective refractive index, resulting in changes in the intensity distribution of the output signal.
