Title: Innovations of Sami T Hendow
Introduction
Sami T Hendow is a notable inventor based in Sunnyvale, CA. He has made significant contributions to the field of optical communication, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Multi-port optical multiplexer element." This invention involves a four-port Wavelength-Division-Multiplexing (WDM) element that can be utilized in various optical communication networks, particularly in bi-directional fiber optic lines. In one embodiment, a single four-port WDM element is paired with an optical amplifier to facilitate bi-directional propagation on the same fiber. Another embodiment incorporates optical attenuators for gain equalization of channels, allowing for the flexibility to add or remove channels. Additionally, input and output ports can be integrated into current-art elements, enabling bi-directional operation with equipment that lacks such capabilities.
Another significant patent is the "Bidirectional optical amplifier having flat gain." This invention describes a bidirectionally amplifying rare earth doped fiber optical amplifier that maintains equalized gain at multiple wavelengths. It is designed for dense wavelength multiplexed bidirectional fiber transmission applications. In one embodiment, a four-port circulator is employed with two amplifying fibers, one for each direction of propagation, along with multiple gratings configured to equalize gain across different wavelengths. Various embodiments utilizing three-port and four-port circulators are also explored, culminating in a more general amplifier device that achieves equal gain at multiple wavelengths.
