Super-Homogeneous Saturation of Microwave-Photonic Gain in Optoelectronic Oscillator Systems
IEEE Photonics Journal, 2012 We show that the saturation characteristic of microwave-photonic gain is “super-homogeneous” such that the gain of a weaker tone saturates more rapidly than that of a stronger tone when both signals are transmitted over an intensity ...

Advanced Materials, EarlyView.A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...

Multi-cavity optoelectronic oscillators using multicore fibers
Optics Express, 2015 We propose the use of both homogeneous and heterogeneous multicore fibers to implement multi-cavity optoelectronic oscillators. We present design equations and examples that show the potential for unique performance in terms of spectral selectivity, tunability and high-frequency operation.
