Dynamic Routing and Spectrum Assignment in Flexible Optical Path Networks
Dynamic Routing Flexible Optical Path Network Spectrum Assignment
2015/5/15
We propose dynamic routing and spectrum assignment algorithms for bitrate-flexible lightpaths in OFDM-based optical networks. The novel algorithms enable dynamic spectrum assignment with more efficien...

Spectrum-Efficiency Bandwidth-Variable Optical OFDM Transport Networks
2015/6/10
We investigated the high spectrum efficiency property of the bandwidth-variable optical OFDM (BV-OOFDM) transport networks. In contrast to mixed-line-rate (MLR) networks, BV-OOFDM enables flexible all...

HPF spectroscopic cuvette dielectric constant
2011/4/21
The adsorption/desorption of Human Plasma fibrinogen (HPF) molecules on biosurfaces was measured in spectroscopic cuvette by a diffractive optical element- (DOE-) based sensor. To characterize the sur...
Characterization of a Mode-Locked Quantum-Dash Fabry-Perot Laser Based on Measurement of the Complex Optical Spectrum
Mode-Locked Quantum-Dash Fabry-Perot Laser Complex Optical Spectrum
2015/7/17
By measuring the complex optical spectrum using a half-rate, sinusoidal modulation method, a mode locked quantum-dash Fabry-Perot laser is characterized for free-running operation and actively mode-lo...
