Ultrafast all-optical modulation of the visible and infrared spectrum with nanorod arrays

Title: Ultrafast all-optical modulation of the visible and infrared spectrum with nanorod arrays

Abstract

Disclosed herein is a method of optical modulation, the method comprising irradiating an optical switch with a control beam at a first control time and irradiating the optical switch with a signal beam at a signal time. The transmitted intensity of the signal beam in a direction depends on the delay time between the first control time and the signal time and the transmitted intensity of the signal beam in the direction is detectably different than a static signal. The optical switch comprises a nanorod array, the nanorod array comprising a plurality of nanorods extending outwardly from a substrate.

Large optical nonlinearity of ITO nanorods for sub-picosecond all-optical modulation of the full-visible spectrum

Journal Article Guo, Peijun [Northwestern Univ., Evanston, IL (United States)] (ORCID:0000000157327061); Schaller, Richard D. [Argonne National Lab. (ANL), Lemont, IL (United States); Northwestern Univ., Evanston, IL (United States)]; Ocola, Leonidas E. [Argonne National Lab.

Optical nonlinearity induced by intense optical excitation of mobile electrons in metallic nanostructures can provide dynamic tuning of their electromagnetic response, which is potentially useful for all-optical information processing. Here we report on the sub-picosecond optical nonlinearity of indium tin oxide nanorod arrays (ITO-NRAs) following intraband, on-plasmon-resonance optical pumping, which enables modulation of the full-visible spectrum with large absolute change of transmission, favorable spectral tunability and beam-steering capability. We semi-quantitatively model the permittivity change, whose large amplitude stems from a significant electron redistribution under intraband pumping due to the low electron concentration. Further, we observe a transient response in themore »« less

A visible semiconductor laser. The visible semiconductor laser includes an InAlGaP active region surrounded by one or more AlGaAs layers on each side, with carbon as the sole p-type dopant. Embodiments of the invention are provided as vertical-cavity surface-emitting lasers (VCSELs) and as edge-emitting lasers (EELs). One or more transition layers comprised of a substantially indium-free semiconductor alloy such as AlAsP, AlGaAsP, or the like may be provided between the InAlGaP active region and the AlGaAS DBR mirrors or confinement layers to improve carrier injection and device efficiency by reducing any band offsets.

Silicon-based visible and near-infrared optoelectric devices

Patent Carey, III, James Edward (Newton, MA); Mazur, Eric [Concord, MA]

In one aspect, the present invention provides a silicon photodetector having a surface layer that is doped with sulfur inclusions with an average concentration in a range of about 0.5 atom percent to about 1.5 atom percent. The surface layer forms a diode junction with an underlying portion of the substrate. A plurality of electrical contacts allow application of a reverse bias voltage to the junction in order to facilitate generation of an electrical signal, e.g., a photocurrent, in response to irradiation of the surface layer. The photodetector exhibits a responsivity greater than about 1 A/W for incident wavelengths inmore »« less
