Rewritable nanoscale oxide photodetector
Nanophotonic devices seek to generate, guide, and/or detect light using structures whose nanoscale dimensions are closely tied to their functionality.1,2 Semiconducting nanowires, grown with tailored optoelectronic properties, have been successfully placed into devices for a variety of applications.3–5 However, the integration of photonic nanostructures with electronic circuitry has always been...
متن کاملObtaining Subwavelength Optical Spots Using Nanoscale Ridge Apertures
Concentrating light into a nanometer domain is needed for optically based materials processing at the nanoscale. Conventional nanometer-sized apertures suffer from low light transmission, therefore poor near-field radiation. It has been suggested that ridge apertures in various shapes can provide enhanced transmission while maintaining the subwavelength optical resolution. In this work, the nea...
متن کاملStudy of optical sensors of the form Al/a-SiC:H/c-Si(n) with high sensitivity
In the present work optical sensors of the form Al/a-SiC:H/c-Si(n), for different thickness of a-SiC:H thin films are studied. More specifically, a-SiC:H thin films were deposited by rf sputtering technique on c-Si(n) substrates for different thickness of the amorphous semiconductor and, subsequently, the samples were annealed in the temperature range from 300C up to 675 C. Experimental measure...
متن کاملParallel optical nanolithography using nanoscale bowtie aperture array.
We report results of parallel optical nanolithography using nanoscale bowtie aperture array. These nanoscale bowtie aperture arrays are used to focus a laser beam into multiple nanoscale light spots for parallel nano-lithography. Our work employed a frequency-tripled diode-pumped solid state (DPSS) laser (lambda = 355 nm) and Shipley S1805 photoresist. An interference-based optical alignment sy...
متن کاملSilicon-based traveling-wave photodetector array (Si-TWPDA) with parallel optical feeding.
We demonstrate silicon-based traveling-wave photodetector arrays (Si-TWPDAs) with parallel optical feeding by integrating multiple Germanium photodetectors. Such Si-TWPDAs feature the merit of high optical saturation power with remaining the large operation bandwidth. The impedance-matched traveling-wave electrode design takes into account the individual Ge photodetector loading effect. Optical...
