Latest Patents

One of her latest patents is titled "Optimization of Optical Transmission Capacity." This invention describes a method for transmitting a coherent optical data signal. It involves receiving a data signal from an interface and encoding it with a forward error correcting (FEC) encoder that utilizes a mix of modulation formats. The FEC encoder generates an FEC encoded signal, which is then used to create modulation symbols. These symbols are spectrally shaped to produce a shaped signal, which is pre-distorted before transmission. The pre-distortion process includes adding a predetermined amount of chromatic dispersion to generate a smoothed signal, which is then transmitted according to the modulation formats.

Another notable patent is "Adaptive Equalization in Coherent Receivers Using a Stokes Space Update Algorithm." This invention features a coherent optical receiver that includes an optical transducer, an adaptive filter, and a processor. The adaptive filter is updated based on a metric derived in Stokes space. The optical transducer receives an optical signal corresponding to a modulated signal of symbols and determines signals corresponding to the first and second polarizations of the optical signal. The adaptive filter recovers equalized signals from these inputs, forming an equalized modulated signal of symbols. The processor calculates a set of Stokes parameters from this signal and updates the adaptive filter accordingly.
