Efficient integrated DC-DC converters for ultra-low voltage energy harvesters
Jayaweera, Herath; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2017-8)
The self-starting on-chip fully integrated ultra-low voltage DC-DC converters for energy harvesting applications presented in literature generally have low efficiency and output power capacity. Any improvement in DC-DC converter circuits in terms of energy efficiency, output power, self-starting modes, and voltage gain will contribute significantly to the widespread application of energy harvesters. Two novel fully integrated, self-starting, ultra-low voltage DC-DC converter topologies and model based optim...
Ultimate fast optical switching of a semiconductor photonic microcavity
Ctistis, Georgios; Yüce, Emre; Alex, Hartsuiker; Maela, Bazin; Julien, Claudon; Jean-Michel, Gerard; Willem L, Vos (2011-07-07)
We present ultrafast pump-probe reflectivity measurements on semiconductor microcavities with a resonance at telecom wavelengths. We observe an ultimate fast red shift and recovery of the cavity resonance due to the instantaneous electronic Kerr effect.
Perfect metamaterial absorber for applications in sustainable and high-efficiency solar cells

The current state of energy is characterized by complex challenges in production processes and environmental issues. With the world population continuing to multiply faster and the globalization process, additional energy production is needed to meet future demands. Solar energy is one of the best sustainable energy resources, which is expected to play a vital role in this scenario. One of the best techniques to harvest this resource is through solar photovoltaic technology, which produces electricity direc...
Ultimate fast optical switching of a planar microcavity in the telecom wavelength range
Ctistis, Georgios; Yüce, Emre; HARTSUİKER, Alex; Claudon, Julien; Bazin, Maela; Gerard, Jean-Michel; Vos, Willem L. (AIP Publishing, 2011-04-18)
We have studied a GaAs-AlAs planar microcavity with a resonance near 1300 nm in the telecom range by ultrafast pump-probe reflectivity. By the judicious choice of pump frequency, we observe an ultimate fast and reversible decrease in the resonance frequency by more than half a linewidth due to the instantaneous electronic Kerr effect. The switch-on and switch-off of the cavity is only limited by the cavity storage time of tau(cav)=0.3 ps and not by intrinsic material parameters. Our results pave the way to ...
