Quantifying Information via Structural Complexity in Optical Beams Using Shannon Entropy

Abstract

We propose a new definition of classical Shannon information that is detached from a particular alphabet and scales with the complexity of the optical field. We experimentally validate these results by reconstructing the wavefront topology.

Programmable photonic chips and applications

“…Finally, the culmination of these innovations and advancements will enable us to fabricate a comprehensive silicon photonic chip that can be directly integrated onto an electronic chip carrier. This would represent a critical milestone in the development of photonic-electronic integrated systems, bringing us closer to an era of high-performance, low-power, and highly-integrated computing platforms [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] . By presenting a detailed roadmap from our early-stage work to our current accomplishments, as well as outlining future development milestones, we aim to offer a comprehensive overview of the Photonic Tensor Core's journey from concept to near-completion.…”

Exciton strain mapping in 2D TMDCs for sensing and photodetection

“…[35][36][37][38][39][40][41][42][43][44][45] Also, it has been demonstrated that the exciton bandgap in TMDCs can be shifted and tuned as an effect of strain. 37,[46][47][48][49] It has been experimentally demonstrated that strain is induced in TMDCs integration on photonic circuits due to the structural profile owing to bandgap tuning. [50][51][52][53][54][55][56][57][58] Here, we demonstrate the study on the effect of strain introduced in tungsten disulfide (WS 2 ) due to heterogeneous integration on silicon nitride waveguide leading to shifting in exciton absorption (1.95 -1.98 eV) using a photodetector device.…”

Demultiplexing OAM beams via Fourier optical convolutional neural network

“…[75][76][77][78][79][80][81][82][83] To enhance the computational efficiency coupled with reduced energy expenditure, optical Fourier convolution is emerging as a competitive contender. [84][85][86][87][88][89][90] The 4f-based optical system offers a rudimentary demonstration of matrix inner-product multiplication allowed for real-time completion at the speed of light, far surpassing the computational speed of any electronic computer of the time.…”
