Phosphorus, a highly reactive element commonly found in match heads, tracer bullets, and fertilizers, can be turned into a stable crystalline form known as black phosphorus. In a new study, researcher...
NIR backscattering measurements using single source-detector optical probe (optods) can detect absorption areas within deep tissue layer. However, such optods, are characterized by large separation di...
A technique using multilevel diffractive gratings to suppress the discrete nature of liquid crystal display (LCD) projection images is demonstrated. The multilevel diffractive gratings, having a cross...
We proposed a scheme of combination of phase regenerator and PMD compensator to the 100-Gbit/s Polarization-Multiplexed DQPSK System to improve its tolerance to PMD. The system performance is effectiv...
Temporal phase modulation of spread stealth signals is proposed to improve optical steganography transmission privacy. It increases an eavesdropper’s difficulty of detecting and intercepting the steal...
Carrier boosting at the receiver enables direct detection optical OFDM (DDO-OFDM) to outperform coherent OOFDM in the nonlinear limit. Boosting also improves the effectiveness of nonlinearity precompe...
A novel digital signal processing algorithm is proposed to improve the performance of digital coherent receivers using single-ended photo detection. The effectiveness of the proposed algorithm is expe...
