Free Space Optic Receiver with Strongly Overlapped Photodetectors’ Field of View
Applied Sciences, 2019 In this study, we designed a mobile free space optic receiver that uses several photodetectors to provide omnidirectional receiving capability. Assuming only one transmitter, it is a receiver which builds a single input multiple output optical channel ...

Numerical modeling of InGaAs/AlGaAs heterostructure for short-wave infrared nBn photodetectors
Journal of the European Optical Society-Rapid PublicationsnBn infrared photodetectors have emerged as a strong alternative to conventional pn and pin-based structures due to their low dark current, fast response, and suppression of Shockley–Read–Hall (SRH) generation pathways. In this study, an InP-based InGaAs/

Low-Frequency Noise Characteristics of AlGaAs/InGaAs Pseudomorphic HEMTs [PDF]
, 2001 The low-frequency noise of InGaAs pseudomorphic HEMTs fabricated on GaAs substrate was studied. The dependence of the noise spectral density on the gate voltage indicates that the channel of the device dominates the low-frequency noise.

A multi-filter system for speech enhancement under low signal-to-noise ratios
, 2009 In this paper, the problem of deteriorating performance of speech recognition under very low signal-to-noise ratios (SNR) is considered. In particular, for a given pre-trained speech recognizer and for a finite set of speech commands, we show that ...

Ultralow-Noise Chopper Amplifier for Seafloor E-Field Measurement
SensorsThe seafloor E-field signal is extremely weak and difficult to measured, even with a high signal-to-noise ratio. The preamplifier for electrodes is a key technology for ocean-bottom electromagnetic receivers.
