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.
As part of the efforts 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 two-dimensional advanced simulations, the detector has been horizontally shifted across a vertically oriented Gaussian beam, which is projected on top of the device. Both electrical and electro-optical simulations have been conducted. These results are promising toward the fabrication of a new generation of photodetector devices.
A type of silicon photodiode has been designed and simulated to probe the optical near field and detect evanescent waves. These waves convey subwavelength resolution. This photodiode consists of a truncated conical shaped, silicon Schottky diode having a subwavelength aperture of 150 nm. Electrical and electro-optical simulations have been conducted. These results are promising toward the fabrication of a new generation of photodetector devices.
