Latest Patents
One of his latest patents is titled "Photonic vector signal generation without precoding." This invention presents a novel and simple photonic vector signal generation scheme at radio frequency (RF) bands, enabled by a single-drive Mach-Zehnder modulator (MZM)-based optical carrier suppression (OCS) without precoding techniques and optical filters. This advancement reduces the complexity of transmitter digital signal processing (DSP). The generation and reception of 16/20/22-Gbaud quadrature-phase-shift-keying (QPSK) vector signals at 16/20/22 GHz have been experimentally demonstrated. The measured bit-error ratio for 16G-baud QPSK vector signals, after transmission over 10-km standard single mode fiber (SSMF), can be maintained under the 7% hard-decision forward-error-correction (HD-FEC) threshold of 3.8×10. Furthermore, compared to conventional precoding schemes, the receiver sensitivity can be enhanced by 4 dB in both back-to-back (BTB) and after 10-km SSMF transmission cases, demonstrating the feasibility and potential application of this technique in radio over fiber (RoF) systems.
Another notable patent is "Imaging cancellation in high-speed intensity modulation and direct detection system with dual single sideband modulation." This invention provides methods and systems for receiving and processing optical signals using a dual single sideband (SSB) modulation scheme. The modulation schemes employed modulate each SSB with their In-phase (I) and Quadrature (Q) components. The methods utilize an adaptive equalizer and an LMS algorithm to remove imaging components of the left and right SSBs provided by the modulators. The adaptive equalizer and LMS algorithm also compensate for linear and nonlinear distortions, employing various algorithms for updating crosstalk coefficients in the equalizer.
