TOM 14 Advances and Applications of Optics and Photonics

Stabilized, short cavity Brillouin ring laser source design for fiber sensing applications

Leonardo Rossi1, Filippo Bastianini2, Gabriele Bolognini1

1National Research Council, IMM Institute, 101 via P. Gobetti, 40129 Bologna Italy; 2Sestosensor s.r.l., 140 via Gesso, 40069 Zola Predosa, Italy

A new pump-seeded, short-cavity Brillouin ring laser source layout intended for Brillouin sensing applications is showcased, showing increased high maximum output (1.5 mW), a strong linewidth narrowing effect (producing light with a linewidth of 10 kHz) and limited RIN (~-145 dB/Hz), providing an ultranarrow, highly stable BRL source that can also be employed as a pump-probe source for BOTDA applications.

16:30 - 16:45

TOM 14 Advances and Applications of Optics and Photonics

Optical characterization of strain sensing cables for Brillouin optical time domain analysis

Filippo Bastianini1, Francesco Falcetelli2, Paweł Bocheński3, Leonardo Rossi4, Raffaella Di Sante2, Gabriele Bolognini4

1Sestosensor s.r.l., 140 via Gesso, 40069 Zola Predosa, Italy; 2Dept. of Industrial Engineering, University of Bologna, Forlì, Italy; 3Fibrain Sp. z.o.o., Wspólna 4A, Rzeszów 35-205, Poland; 4Consiglio Nazionale delle Ricerche, IMM Institute, 101 via P. Gobetti, 40129 Bologna Italy

Two innovative optical fibre cable layouts designed to improve BOTDA strain measurement accuracy through improved strain transfer efficiency are presented, discussed and tested through experiments, analytical and numerical modelling. The second improved design presents good features to minimize the mismatch between measured and actual strain.

TOM 14 Advances and Applications of Optics and Photonics

An analytical approach for unveiling the role of intrinsic and extrinsic factors on photoresponse of graphene transistors.

Metal-contacted graphene plays a very important role in high-performance graphene-based optoelectronic devices. A number of parameters affect the photoresponse, and a detailed understanding of the intricate interdependence of these parameters is crucial for designing and predicting the performance of graphene-based optoelectronic devices. In this work, we develop an advanced analytical model that integrates the effects of electrical, optical, optoelectronic, and contact resistance to determine the resultant photoresponse of graphene devices. Based on this method, the influence of different external stimuli on the photocurrent of the device can be analyzed.

TOM 14 Advances and Applications of Optics and Photonics

On polarization characteristics of highly focused fields concentrated along the axis

Rosario Martínez-Herrero1, Artur Carnicer2, Ignasi Juvells2, Angel S, Sanz1

1Universidad Complutense, Spain; 2Universitat de Barcelona

After having proven that an uncertainty relation holds for the on-axis power content of highly focused fields, in this Communication we explore and discuss the consequences of such a relation concerning the polarization state characterizing the fields that satisfy it.
