Spontaneous emission control in high-extraction efficiency plasmonic crystals
Hideo Iwase, Dirk Englund, Jelena Vuckovic
We experimentally and theoretically investigate exciton-field coupling for the surface plasmon polariton (SPP) in waveguide-confined (WC) anti-symmetric modes of hexagonal plasmoni…
Local tuning of photonic crystal cavities using chalcogenide glasses
Andrei Faraon, Dirk Englund, Douglas Bulla +5
We demonstrate a method to locally change the refractive index in planar optical devices by photodarkening of a thin chalcogenide glass layer deposited on top of the device. The me…
Terahertz Room-Temperature Photonic Crystal Nanocavity Laser
Dirk Englund, Hatice Altug, Ilya Fushman +1
We describe an efficient surface-passivated photonic crystal nanocavity laser, demonstrating room-temperature operation with 3-ps total pulse duration (detector response limited) a…
Genetic Optimization of Photonic Bandgap Structures
Joel Goh, Ilya Fushman, Dirk Englund +1
We investigate the use of a Genetic Algorithm (GA) to design a set of photonic crystals (PCs) in one and two dimensions. Our flexible design methodology allows us to optimize PC st…
Local Quantum Dot Tuning on Photonic Crystal Chips
Andrei Faraon, Dirk Englund, Ilya Fushman +3
Quantum networks based on InGaAs quantum dots embedded in photonic crystal devices rely on QDs being in resonance with each other and with the cavities they are embedded in. We dev…
Dynamics of Quantum Dot Photonic Crystal Lasers
Bryan Ellis, Ilya Fushman, Dirk Englund +3
Quantum dot photonic crystal membrane lasers were fabricated and the large signal modulation characteristics were studied. We find that the modulation characteristics of quantum do…
