Latest Patents
Frampton's latest patents include a "Method and apparatus for optical signal processing using an optical tapped delay line." This invention involves an Optical Tapped Delay Line (OTDL) that resolves multiple wavelength signals with extremely narrow wavelength spacing. The OTDL is combined with other optical devices to facilitate various applications, such as multiplexing and de-multiplexing multi-channel signals, adding or dropping signals from multi-channel optical signals, and specialized coding processing. The OTDL spatially separates individual channels, allowing for separate processing on each channel. The invention has particular applications in dense wavelength division multiplexing (DWDM), significantly improving the quantity of information that can be carried while enhancing signal quality.
Another notable patent is the "Wavelength division multiplexing add-drop multiplexer using an optical tapped delay line." This invention integrates an OTDL with other optical apparatuses to create an add-drop multiplexer for wavelength division multiplexing fiber optic networks. Each output beam of the OTDL is spatially distinguishable in free space, enabling the selection of one or more optical beams for adding or dropping. The system can be configured as a fixed or tunable single-channel or multi-channel add/drop system, or even a fully programmable add/drop system.
