Absorption Enhancement in Ultrathin Crystalline Silicon Solar Cells with Antireflection and Light-Trapping Nanocone Gratings
Solar cells light trapping antireflection crystalline silicon absorption enhancement nanocone gratings
2015/8/7
Enhancing the light absorption in ultrathin-film silicon solar cells is important for improving efficiency and reducing cost. We introduce a double-sided grating design, where the front and back surfa...

We theoretically investigate the enhancement of optical absorption in thin-film organic solar cells in which the top transparent electrode is partially substituted by a periodic metallic grating...
Bandwidth Enhancement of Distributed Reflector Lasers at Low Bias Current by Optical Injection Locking
Lasers distributed-feedback Lasers injection-locked Quantum-well wire and -dot devices
2015/6/4
By optical-injection-locking, the bandwidth enhancement of Distributed-Reflector lasers with quantum-wire-like active regions was demonstrated. The bandwidth was increased to >15-GHz at a 5-mA bias, w...
Simultaneous ER Enhancement and Frequency Stabilization Scheme for Directly Modulated DFB Lasers
Fiber optics communications Fiber optics links subsystems
2015/6/4
A simultaneous extinction-ratio enhancement and frequency stabilization scheme is proposed for directly modulated DFB lasers at the optical line terminal to enhance signal quality and to stabilize opt...
Optical Absorption Enhancement in Amorphous Silicon Nanowire and Nanocone Arrays
Optical Absorption Enhancement Amorphous Silicon Nanowire Nanocone Arrays
2015/8/10
Hydrogenated amorphous Si (a-Si:H) is an important solar cell material. Here we demonstrate the fabrication of a-Si:H nanowires (NWs) and nanocones (NCs), using an easily scalable and IC-compatible pr...
Data Rate Enhancement of RSOA-based WDM PON Systems using Feed-forward Equalizer and Forward Error Correction
WDM PON Systems Feed-forward Equalizer
2015/8/6
Effect of FFE and FEC to enhance the data rate of RSOA was investigated. 4.75Gbit/s was achieved by 0.6GHz RSOA using 4-tap FFE and ~14% FEC.
