Nanoscale Al-Si Truncated Conical Photodetector with Subwavelength Aperture

 

Abstract: A new type of silicon photodiode has been designed and simulated in order to probe the optical near field, and detect evanescent waves. These waves convey sub-wavelength resolution. This photodiode consists in a truncated conical shaped, silicon Schottky diode having a subwavelength aperture of 150 nm. In this paper, electrical and electro-optical simulations have been conducted. These results are promising towards the fabrication of a new generation of photodetector devices.
