Latest Patents

Among his latest patents is an optical add-drop multiplexing technique and a wavelength division multiplexing optical link utilizing this technique. This invention features an optical add-drop multiplexer (OADM) designed to efficiently manage wavelength groups for each node within multiplexed input channels. The OADM includes a wavelength group demultiplexer that separates input channels into groups, allowing for the dropping of specific channel groups while passing others through. Additionally, it incorporates a channel selector and a channel multiplexer to facilitate the selection and multiplexing of channels, ultimately reducing the time required to extend channel capacity. This innovation is particularly beneficial for constructing wavelength division multiplexing (WDM) optical links.

Another notable patent is an optical attenuator that employs an isolator, which is part of an optical communications system. This device controls the intensity of an input optical signal by utilizing a Faraday rotator that adjusts the polarization rotation angle based on the intensity of an applied magnetic field. The system includes a magnetic field generator and a power supply that regulates the current intensity, allowing for precise control over the optical signal's attenuation. The compact design of the optical attenuator makes it easy to integrate into existing systems.
