A skew compensator is proposed and experimentally demonstrated for coherent front-end, which improved tolerance from ± 3 to ± 21ps at 0.2dB Q-penalty even with 21,000ps/nm CD and 90ps DGD on 112Gb/s...
New multiphoton microscopy using CARS (Coherent Anti-Stokes Raman Scattering) spectroscopy is described. In CARS microscopy, the image of molecular vibration that is sensitive to the molecular spices ...
We have studied primary processes of ultrafast photoisomerization reactions of photoactive yellow protein (PYP) and visual rhodopsin (Rh) as well as ultrafast photoinduced electron transfer reactions ...
We asses through Monte Carlo simulations PDM-QPSK/OOK and DQPSK/OOK Hybrid systems perfor-mance. DQPSK works better with optimal dispersion-management. PDM-QPSK is more robust to system impair-ments.
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
We present 40-km range, 1-m spatial resolution and highly sensitive measurement based on phase-noise-compensated OFDR that employs a concatenative reference method.
By using PolMux-RZ-QPSK modulation format and digital coherent detection, we have demonstrated 20×112Gbit/s DWDM transmission over 1540km of SSMF without using Raman amplification or optical dispersio...
A 53-km Simplex-coded distributed temperature sensor based on coherent detection of Brillouin frequency shift is demonstrated with 1.1 K and 35 m resolutions, using only 10 mW input peak power.
We propose a novel maximum a posteriori probability (MAP) detector in coherent WDM systems, which exhibits significant improvement in back-to-back receiver sensitivity, chromatic dispersion and phase ...
We extended a pilot symbol frequency offset estimation scheme and applied it in combination with a pilot subcarrier compensator. Optimum system sensitivity was found up to few 100MHz frequency offset.
Coherent detection combined with digital signal processing (DSP) is a symbiotic relationship. Not only does DSP relax the requirements on the coherent receiver but it permits digital compensation of f...
A two-level system coupled to a one-dimensional continuum is investigated. By using a real-space model Hamiltonian, we show that spontaneous emission can coherently interfere with the continuum modes ...
