5G/NGPON Evolution and Convergence: Developing on Spatial Multiplexing of Optical Fiber Links for 5G Infrastructures Fiber Integr. Opt. (IF 1.7) Pub Date : 2020-01-02 Thomas Lagkas,Dimitrios Klonidis,Panagiotis Sarigiannidis,Ioannis Tomkos
ABSTRACT The offering of demanding telecommunication services as promised by the 5G specifications raise the necessity for high capacity, flexible, adaptive, and power conserving fronthaul. Toward this goal, the role of the passive optical network which is responsible for interconnecting the central office (CO) with the cell-sites is crucial. Among the latest related technologies that need to be integrated

Demonstration of Automated Adjustment and Coupling of Fiber Array to PICs Based on the Detection of Edges Fiber Integr. Opt. (IF 1.7) Pub Date : 2020-01-02 Jozef Chovan,Martin Tomáška,František Uherek,Daniel Haško,Dana Seyringer,Lenka Gajdošová,Eduard Koza,Jozef Pavlov
ABSTRACT Progress in integrated photonics enables development of photonics integrated circuits (PIC) with new unique properties and overcomes current limits in information and communication technologies. The effective coupling of optical radiation between telecom optical fiber and photonic integrated circuits is necessary. To address these challenges, we present our concept of photonics integrated

Sensors of Encoding and Decoding Based on Superstructure Fiber Bragg Gratings Modulated in Amplitude and Phase for applications in systems OCDMA - 63 chip Fiber Integr. Opt. (IF 1.7) Pub Date : 2019-12-23 Antonio Francisco Gomes Furtado Filho, Juscelino Sales Chaves, José Rubens Rodrigues de Sousa, Giannini Italino Alves Vieira, Marcio de Melo Freire, Antonio Sergio Bezerra Sombra
In this paper, we report a series of incremental optical coding and decoding sensors using their respective fiber Bragg grating superstructure (SS-FBG). We performed a comparative study of the encoding/decoding bipolar and unipolar sequences using these grids. The modulation in the refractive index can be changed by discrete jumps in phase (± π) or variations in the amplitude of the specific grid regions
