Multi-Wavelength optical probing of action potential distribution

Multi-optical-wavelength ultrasound-modulated optical tomography: a phantom study.

We used multiple optical wavelengths to study ultrasound-modulated optical tomography (UOT) in tissue phantoms. By using intense acoustic bursts and a CCD camera-based speckle contrast detection technique, we observed variations of the ultrasound-modulated signal at various optical absorptions. The experimental variations were found to be highly correlated with predictions from Monte Carlo simu...

Transmission performance of transparent multi-wavelength optical cross-connected networks

The transmission performance of regular two-connected multi-hop transparent optical networks in uniform traffic under hot-potato, single-buffer deflection routing schemes is presented. Manhattan Street (MS) Network and ShuffleNet (SN) are compared in terms of bit error rate (BER) and packet error rate (PER) both analytically and by simulation. We implement a novel strategy of analysis, in which...

Performance Comparison of Multi-wavelength Conversion Using SOA-MZI and DSF for Optical Wavelength Multicast

The electronic layer multicast is going to face the speed and capacity bottleneck of the future optical data networks. Transparent optical wavelength multicast by multi-wavelength conversion is an effective way of achieving data multicast in the optical domain without any optical-electronic-optical conversion. In this paper, two multiple wavelength conversion technologies for 10 Gb/s data rate ...
