We have developed a new simulation methodology for predicting shot noise intensity in Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET). In our approach, shot noise in MOSFETs is calculated by employing the two dimensional device simulator MEDICI in conjunction with the shot noise model of p-n junction. The accuracy of the noise model has been demonstrated by comparing simulation resul...

We propose a nonlinear fiber system for shot-noise limited, all-optical intensity-noise reduction and signal amplification. The mechanism is based on the accumulation of different phase shifts between orthogonal polarization modes in polarization-maintaining amplifier combination with an implemented sinusoidal transmission-function. resulting correlation input intensity-fluctuations transmissio...

In low-light conditions, it is known that Poisson noise and quantization noise become dominant sources of noise. While intensity difference is usually measured by Euclidean distance, it often breaks down due to an unnegligible amount of uncertainty in observations caused by noise. In this paper, we develop a new noise model based upon Poisson noise and quantization noise. We then propose a new ...

A technique to improve the dynamic range of a photonic microwave bandpass filter is proposed and experimentally demonstrated. The filter is implemented based on phase modulation to intensity modulation conversion using fiber Bragg gratings (FBGs) serving as frequency discriminators, with the optical carriers located at the left or right slopes of the FBGs, to generate positive or negative tap c...

A systematic treatment of the influence optical feedback (OFB) and ratio radiative non-radiative recombination lifetime (τr/τnr) on relative intensity noise (RIN) system dynamics a semiconductor laser (SL) is presented. We found that τr/τnr causes significant change in noise, states, route to chaos such system. Laser transit from continuous wave (CW) periodic oscillation (PO) becomes faster ter...

We investigate reduction of mode partition noise of a spectrally sliced Fabry-Perot laser diode (FP-LD) for application to seeded DWDM systems. The proposed scheme for the noise reduction incorporates a fiber-based Mach-Zehnder interferometer (MZI) and a reflective semiconductor optical amplifier (RSOA). The MZI enables to reduce a relative intensity noise (RIN) more than 3 dB with better noise...
