Polarization state and its effect on the optical neural network of a semiconductor laser in a chaos state
Source abstract
Abstract
The operation of an optical neural network via feed-forward (FF) configuration is experimentally simulated in the laboratory. We test the FF setup using optical injection and examine the behavior of follower laser diodes (FLDs) subjected to chaotic modulation. The last two laser diodes are exposed to different weights of chaotic modulated signals through optical filtration and the angle of the influencer laser. We observe a maximum FWHM of 1.8 GHz for FLD at an angle (C) of 70° and a modulated signal attenuation of −12 dB. We calculate the correlation between the influencer lasers (ILDs) and FLDs to determine the synchronization state. Results indicate fluctuations between negative and positive values, with the best correlation value being −0.4. These results confirm antisynchronized ILD-FLDs, which is crucial for ensuring privacy in transmitting units within a chaotic optical communication system simulating an optical neural network.
