Paper Abstract

Persisting in the large trend to enhance the Near-field Scanning Optical Microscopy and the detection of evanescent waves, a silicon Schottky diode, shaped as a truncated trapezoid photodetector, and sharing a subwavelength pin-hole aperture, has been designed and simulated. Using Finite Elements Method and 3D advanced simulations, the detector has been horizontally shifted across a vertically oriented Gaussian beam, which is projected on top of the device. Electrooptical simulations have been conducted. These results are promising towards the fabrication of a new generation of photodetector devices.
