Noise Comparison of RF Photonic Filters Based on Coherent and Incoherent Multiwavelength Sources
(IEEE, 2012)
A filtered microwave photonic (MWP) link
implemented with an optical frequency comb as a multitap
optical source offers a significant improvement in noise
characteristics when compared to a spectrally sliced broadband
incoherent ...
Spectral broadening enhancement in silicon waveguides through pulse shaping
(Optical Society of America, 2012)
Spectral broadening in silicon waveguides is usually inhibited at telecom wavelengths due to some adverse effects related to semiconductor dynamics, namely, two-photon and free-carrier absorption (FCA). In this Letter, our ...

Oxygen doping-induced photogeneration loss in P3HT:PCBM solar cells
(Elsevier, 2012-05)
This work investigates the loss in performance induced by molecular oxygen in bulk heterojunction solar cells. We observe that upon exposure to molecular oxygen both formation of P3HT+:O2− complex and metal oxidation at ...
