All-optical THz wave switching based on CH3NH3PbI3 perovskites
Hybrid structures of silicon with organic-inorganic perovskites are proposed for optically controllable switching of terahertz (THz) waves over a broad spectral range from 0.2 to 2THz. A 532-nm external laser was utilized to generate photoexcited free carriers at the devices and consequentially to control the terahertz amplitude modulation, obtaining a depth of up to 68% at a laser irradiance o...
متن کاملCH3NH3PbI3 perovskites: Ferroelasticity revealed
Ferroelectricity has been proposed as a plausible mechanism to explain the high photovoltaic conversion efficiency in organic-inorganic perovskites; however, convincing experimental evidence in support of this hypothesis is still missing. Identifying and distinguishing ferroelectricity from other properties, such as piezoelectricity, ferroelasticity, etc., is typically nontrivial because these ...
متن کاملAll-Optical Packet Switching Network based on Optical Code Processing
This work introduces a significant improvement for optical packet switching network based on OC processing. The key point of this method is the generalization of the optical label switching concept to forward optical packet without label swapping and O/E/O procedure. Our proposed method simplifies the design of switch devices in optical domain and packet forwarding process which speeds up packe...
متن کامل17 THz Continuous - Wave Optical Modulator
We use coherently rotating hydrogen molecules and demonstrate a continuous-wave (CW) optical modulator at a frequency of 17.6 THz that can modulate any laser within the optical region of the spectrum. The molecules are prepared in a coherent state by using two intense laser beams spaced by the Raman transition frequency inside a high finesse cavity. PACS numbers: 42.65.Dr, 42.65.Re, 42.50.Gy
متن کاملAll-optical switching on a silicon chip.
We present an experimental demonstration of fast all-optical switching on a silicon photonic integrated device by employing a strong light-confinement structure to enhance sensitivity to small changes in the refractive index. By use of a control light pulse with energy as low as 40 pJ, the optical transmission of the structure is modulated by more than 97% with a time response of 450 ps.
