A Novel Wireless over Fiber Access Architecture Employing Moving Chain Cells and RoF Technique for Broadband Wireless Applications on the Train Environment
Networks ptical communications
2015/5/26
We have demonstrated a hybrid optical/wireless system based on moving chain cells and radio-over-fiber techniques. This scheme can improve power efficiency, cell-edge coverage,system throughput and fl...
Low Power and Broadband 2 X 2 Silicon Thermo-Optic Switch
Low Power Broadband Thermo-Optic Switch
2015/5/21
We present a 2X2 silicon thermo-optic switch which requires a switching power of only ～12.5 mW and has a response time of 5.4 μs. The measured extinction ratio of the switch is >～20 dB across the C an...
Architecting Green Broadband Cable Access Network:Energy-Delay Trade-off
Green Broadband Cable Access Network Energy-Delay Trade-off
2015/5/18
We propose and investigate an energy-saving algorithm for DOCSIS-3.0 cable access networks. Numerical simulations indicate a possible 17.4% energy-saving for 8000 cable modems,but also reveal a fundam...

2015/6/4
In large-scale hybrid wireless-optical broadband access networks, the availability of wireless links and optical links varies considerably. Availability-aware routing can significantly improve availab...
Compact and Broadband Coherent Receiver Front-End for Complete Demodulation of a 1.12-Terabit/s Multi-Carrier PDM-QPSK Signal
Broadband Coherent Receiver Multi-Carrier PDM-QPSK Signal
2015/7/20
We report a compact coherent receiver front-end consisting of an integrated 4x40 arrayed-waveguide-grating array following a polarization-diversity hybrid for complete demodulation of a 1.12-Tb/s mult...
Simultaneous Broadband Wired/Millimeter-Wave Band Transmission with Broadcasting Signal Using Direct ASE Modulation of an RSOA for WDM/SCM-PON Systems
Broadband Wired/Millimeter-Wave Band Transmission Broadcasting Signal RSOA for WDM/SCM-PON Systems
2015/7/17
A novel scheme of simultaneous broadband data transmission for both wired and millimeter-wave band with broadcasting signal is proposed based on a directly modulated amplified spontaneous emission usi...
