Ultrahigh Q-factor Ge11.5As24Se64.5 chalcogenide glass photonic crystal cavity embedded in silica
Photonic crystals (PhCs) have attracted much attention for their ability to manipulate light, for example structures containing ultrahigh Q-factor cavities allow low threshold all-optical switching as has been demonstrated in 2-D PhCs fabricated in air-clad silicon membranes. However, the strong two-photon (TPA) and free-carrier absorption (FCA) in silicon has meant that optical switching has so far been due to the slow thermal nonlinearity exacerbated by the low thermal mass and poor heat...[Show more]
