Enhanced confined microwave transmission by single subwavelength apertures
(Bilkent University, 2005)Grating-coupling phenomena between surface plasmons and electromagnetic waves are studied in the microwave spectrum using metallic circular apertures surrounded by an array of grooves. The measurements are performed in ... -
Idler-efficiency-enhanced long-wave infrared beam generation using aperiodic orientation-patterned GaAs gratings
(Optical Society of America, 2016)In this paper, we design aperiodic gratings based on orientation-patterned gallium arsenide (OP-GaAs) for converting 2.1 μm pump laser radiation into long-wave infrared (8-12 μm) in an idler-efficiency-enhanced scheme. ... -
Plasmonic gratings for enhanced near infrared sensitivity of Silicon based Schottky photodetectors
(IEEE, 2011)Schottky photodetectors have been intensively investigated due to their high speeds, low device capacitances, and sensitivity in telecommunication standard bands, in the 0.8μm to 1.5μm wavelength range. Due to extreme cost ... -
Plasmonic materials based on ZnO films and their potential for developing broadband middle-infrared absorbers
(American Institute of Physics Inc., 2014)Noble metals such as gold and silver have been extensively used for plasmonic applications due to their ability to support plasmons, yet they suffer from high intrinsic losses. Alternative plasmonic materials that offer ... -
Polymeric waveguide Bragg grating filter using soft lithography
(Optical Society of American (OSA), 2006)We use the soft lithography technique to fabricate a polymeric waveguide Bragg grating filter. Master grating structure is patterned by e-beam lithography. Using an elastomeric stamp and capillary action, uniform grating ...
