Latest Patents
One of her latest patents is titled "Method and system for setting timing of phase modulation of xPSK transmitter." This invention provides a method for setting the timing of phase modulation by a target phase modulator within an optical transmitter that performs 2-order phase shift keying. The method involves feeding a specific pattern to the optical transmitter, allowing it to emit an optical carrier in accordance with that pattern. The optical carrier is then received by a delay interferometer, where a pair of light signals emitted from constructive and destructive outputs is converted into an electrical signal. The peak-to-peak value of this electrical signal is detected, and the timing of the phase modulation is set to minimize this value.
Another notable patent is "DPSK modulation-demodulation method, and optical communication device and optical communication system using the same." This invention focuses on an optical communication device and system that utilizes DPSK modulation while being cost-effective, compact, and energy-efficient. The N:1 multiplexer generates a serial signal by multiplexing a parallel signal coded by the DPSK modulation coding units bit by bit on a time division basis. The electric-phase modulation optical converter then converts this serial signal into a phase modulation light, which is decoded by the N-bit delay interferometer.
