Microwave photonic integrator based on a multichannel fiber Bragg grating.
We propose and experimentally demonstrate a microwave photonic integrator based on a multichannel fiber Bragg grating (FBG) working in conjunction with a dispersion compensating fiber (DCF) to provide a step group delay response with no in-channel dispersion-related distortion. The multichannel FBG is designed based on the spectral Talbot effect, which provides a large group delay dispersion (G...
متن کاملPerformance of a 1Gbps Optical Direct Sequence CDMA Based on Sampled Fiber Bragg Grating
This paper presents the experimental demonstration of a 1 Gbps Direct Sequence Optical Code Division Multiple Access (DS-OCDMA) system using pulsed coherent source. Encoding and decoding using Prime Sequence codes are achieved by Sampled Fiber Bragg Gratings (S-FBGs). The encoders/decoders have been designed with OptiGrating software and realized with Phase Mask Process. BER measurements have b...
متن کاملSampled Fiber Bragg Grating spectral synthesis.
In this paper, a technique to estimate the deformation profile of a Sampled Fiber Bragg Grating (SFBG) is proposed and experimentally verified. From the SFBG intensity reflection spectrum, any arbitrary longitudinal axis deformation profile applied to a SFBG is estimated. The synthesis algorithm combines a custom defined error metric to compare the measured and the synthetic spectra and the Par...
متن کاملFiber-Bragg-Grating Based Optical Amplifiers
In this chapter, we propose several schemes for fiber amplifiers which are all using fiber Bragg gratings (FBGs) as the key elements for their advantages of better uniformity, higher contrast ratio and lower cost. Several applications using FBG-based fiber amplifiers are also introduced. Therefore, this chapter initiates the overview of FBGs characteristics in Sec. 1, then addresses the FBGs pl...
متن کاملA fiber-based ratiometric optical cardiac mapping channel using a diffraction grating and split detector.
Optical fiber-based mapping systems are used to record the cardiac action potential (AP) throughout the myocardium. The optical AP contains a contraction-induced motion artifact (MA), which makes it difficult to accurately measure the action potential duration (APD). MA is removed by preventing contraction with electrical-mechanical uncoupling drugs, such as 2,3-butanedione monoxime (BDM). We d...
