Spectral response modification of TiO₂ MSM photodetector with an LSPR filter.
We fabricated UVB filtered TiO₂ MSM photodetectors by the localized surface plasmon resonance effect. A plasmonic filter structure was designed using FDTD simulations. Final filter structure was fabricated with Al nano-cylinders with a 70 nm radius 180 nm period on 360 nm SiO₂film. The spectral response of the TiO₂ MSM photodetector was modified and the UVB response was reduced by approx. 60% w...
متن کاملLSPR enhanced MSM UV photodetectors.
We fabricated localized surface plasmon resonance enhanced UV photodetectors on MOCVD grown semi-insulating GaN. Plasmonic resonance in the UV region was attained using 36 nm diameter Al nanoparticles. Extinction spectra of the nanoparticles were measured through spectral transmission measurements. A resonant extinction peak around 300 nm was obtained with Al nanoparticles. These particles gave...
متن کاملNovel Electrically Tunable MSM Photodetector for Resolving WDM Channels
We present a novel MSM (metal-semiconductor-metal) based tunable photodetector for discrimination between two wavelengths with a 365GHz channel spacing. If integrated with CMOS circuits, this photodetector has the potential to perform high-speed channel switching in WDM-based systems. With increasing data traffic load in telecommunications networks, wavelength division multiplexing (WDM) is ess...
متن کاملAn Ensemble Monte Carlo Model to Calculate Photocurrent of MSM Photodetector
In this paper, we present an ensemble Monte Carlo model to calculate the time response for GaAs MSM photodetectors. Our model includes two valleys and two bands for electrons and holes respectively. We simulate optical pulse absorption and trajectory of carriers to calculate electron and hole currents. Also, we calculate the effect of different voltages and optical pulses on photocurrent. To va...
متن کاملAn Optimal Modification of a Kalman Filter
The purpose of a time scale is to form a virtual clock from an ensemble of physical clocks that are compared with one another at a sequence of dates, where a date is the reading of a clock as determined by counting its oscillations. The virtual clock is defined as an offset from one of the physical clocks, the offset being computed from the comparison measurements by some algorithm. The usual g...
