Simulation of Ge on Si Photodiode with photon-trapping micro-nano holes with -3dB bandwidth of >60 GHz at NIR wavelength
Ekaterina Ponizovskaya Devine, Toshishige Yamada, Shih-Yuan Wang +1
The study proposes an ultra-thin back side illuminated (BSI) and top-illuminated, Ge on Si photodetector (PD), for 1 to 1.4 microns wavelength range. The Ge thickness of 350 nm all…
CMOS image sensor with micro-nano holes to improve NIR optical efficiency: micro-holes on top surface vs on bottom
E. Ponizovskaya Devine, Ahasan Ahamad, Ahmed Mayet +5
We study the nano- and micro-structures that increase the optical efficiency of the CMOS image pixels in visible and infrared. We consider the difference between the micro-holes at…
Single Micro-hole per Pixel for Thin Ge-on-Si Image Sensor with Enhanced Sensitivity upto 1700 nm
Ekaterina Ponizovskaya-Devine, Ahmed S. Mayet, Amita Rawat +5
We present a Ge-on_Si CMOS image sensor with backside illumination for the near-infrared electromagnetic waves, wavelengths range 300-1700nm, detection essential for optical sensor…
Phase stochastic resonance in coherent QKD signal transmission with a crosstalk noise in multicore fiber
E Ponizovskaya-Devine
The study considers the new effect of phase stochastic resonance in a linear system with multiple external signals that can influence quantum communication. The phase stochastic re…
Optimization of CMOS image sensors with single photon-trapping hole per pixel for enhanced sensitivity in near-infrared
E. Ponizovskaya Devine, Ahasan Ahamed, Ahmed S. Mayet +7
The optimization of silicon photodiode-based CMOS sensors with backside-illumination for 300-1000 nm wavelength range was studied. It was demonstrated that a single hole on a photo…
Mid-infrared photodetector based on 2D material metamaterial with negative index properties for a wide range of angles near vertical illumination
E. Ponizovskaya Devine
We present the vertically illuminated Si compatible mid-infrared photodetectors based on graphene that forms negative-index metamaterial. The coupling into a 2D layer at the angles…
