Towards Cryophotonics: Experimental Characterization of SOA at Cryogenic Temperatures
IEEE Photonics Journal, 2023 We present an experimental system study of the influence of cryogenic temperatures on the performance of a commercial Semiconductor Optical Amplifier (SOA) over the range 240 K – 70 K.

Excess noise for coherent radiation propagating through amplifying random media [PDF]
, 1999 A general theory is presented for the photodetection statistics of coherent radiation that has been amplified by a disordered medium. The beating of the coherent radiation with the spontaneous emission increases the noise above the shot-noise level.

Impact of AlGaN Barrier Thickness and Substrate Material on the Noise Characteristics of GaN HEMT
IEEE Journal of the Electron Devices Society, 2022 In this paper, the impact of AlGaN barrier thickness ( $\text{t}_{\mathrm{ AlGaN}}$ ) and substrate leakage on the noise conductance and noise figure in GaN High Electron Mobility Transistor (HEMT) is investigated.

Effects of DUT mismatch on the noise figure characterization: A comparative analysis of two Y-factor techniques [PDF]
, 2002 Device mismatch seriously degrades accuracy in noise figure characterization. The suitability of corrections to the gain definitions for a more precise noise figure evaluation for mismatched devices is investigated and compared to classical techniques ...

Gain and Noise Figure Performance of Erbium-Doped Fiber Amplifiers [PDF]
Kirkuk Journal of Science, 2008 Fiber loss is a fundamental limitation in realizing long haul point–to-point fiber optical communication links and optical networks. One of the advanced technologies achieved in recent years is the advent of erbium doped fiber amplifiers (EDFAs) that has

Fault-tolerant quantum computation versus Gaussian noise [PDF]
, 2008 We study the robustness of a fault-tolerant quantum computer subject to Gaussian non-Markovian quantum noise, and we show that scalable quantum computation is possible if the noise power spectrum satisfies an appropriate "threshold condition." Our ...
