In order to verify the simulated results, a MATLAB mathematical model is also used to aid the design of the SOA. Using the model, the gain difference between simulated and mathematical results in the unsaturated
The present paper investigates output bit patterns using MATLAB. Amplitude Modulation (AM) is calculated and found to be as low as 0.007 dB for unsaturated gain of 10 dB of the QDSOA. A maximum Quality factor 27 dB is calculated for 5mW control power. The paper also investigates the effect...
Optoelectronic fibres While the glass-clad semiconductor fibres are favoured for optical use43, it is challenging to form well defined interfaces between insulators, semiconductors and conductors for in-fibre optoelectronic devices, mainly owing to the limited control on the viscosities of these materials...
Normalized input image patterns are generated with MATLAB by turning off individual pixels and adding Gaussian white noise based on the ideal patterns. Each pattern’s value is mapped with a various standard deviations range of 0–1, corresponding to the normalized optical power. Weight values are ...
(running MATLAB®, for example, for convenience). Light from the VCSEL is collimated by a lens, circularly polarized, passed through the vapor cell, and finally detected with a silicon photodiode. In one embodiment, a transimpedance amplifier converts the photocurrent to a voltage, which is ...
