However multiple wireless signals which have the same carrier frequency cannot propagate over a single optical fiber, such as MIMO signals feeding multiple antennas in the fiber wireless (FiWi) system. A novel optical single-sideband frequency translation (OSSB-FT) technique is proposed to solve this problem. In this paper, three wireless MIMO signals are designed to transport over a 20 km standard single mode fiber (SMF) using the OSSB-FT technique by one optical source. Each wireless MIMO signal is with a 2.44 GHz carrier frequency, 1 Gb/s data rate, and 16 quadrature amplitude modulation (QAM). The crosstalk between the wireless MIMO signals is excluded, since each wireless MIMO signal is carried on a specific optical wavelength.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131704787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, peak power flatness was also improved for BEFL with a TBF. By tuning the center wavelength of the TBF, the BEFL operation can be tuned to any wavelength within 40nm range in comparison to only 5nm for the BEFL without a TBF as the laser operation is dictated by the self-lasing cavity mode.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diffraction peaks corresponding to crystalline Er-Si-O were clearly detected in X-ray diffraction measurements. Er-related infrared luminescence was observed at around 1.52 μm at room temperature. This luminescence of the crystalline Er-Si-O compound on Si was due not to direct excitation of the 4f shell of Er3+, but to excitation of the host Si, i.e. indirect excitation. The observed luminescence was very intense compared with that of a sample prepared by a wet-chemical method using ErCl3. The Er-related PL spectra also showed several peaks at room temperature, which reflected the splitting patterns of ground manifolds (4I15/2) for the 4f11 shell of Er3+. Significant differences in peak wavelengths between the crystalline Er-Si-O compound on Si substrate and Er-doped Si on Si substrate (Si:Er:O/Si) grown by molecular beam epitaxy were observed in the PL spectra at 77 K. In addition, temperature quenching of Er-related infrared luminescence was greatly reduced in the crystalline Er-Si-O compound prepared using the simple method. Finally, a new electron spin resonance spectrum was detected for the crystalline Er-Si-O compound on silicon substrate, thought to be related to the presence of Er atoms in the compound.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122491887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 32 Channels DWDM system has been numerically compared for pre, post and symmetrical dispersion compensation schemes with 50 GHz channel separation to characterize this modulation format for 40 Gb/s data rate. The transmission link is designed first with perfect compensation and then with under-compensation. The performance has been evaluated using Q value as the major parameter, by varying the input power for different transmission distances with different dispersion compensation schemes. It is observed that even under four-wave mixing(FWM) degradation, DRZ based DWDM system shows acceptable performance beyond 1000 Km. This paper reports the superiority of DRZ format over the conventional NRZ /RZ schemes in both cases.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122320206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, higher doping of Er3+ ions would cause erbium ion clustering due to network structure of silica which has strong Si-O-Si covalent bonds thus reduced the luminescence emission intensity. Network structure of silica can be overcome by introducing ZrO2 as co-host material in silica glass matrix which helps Er3+ ions dispersed homogenously. Hence, avoiding the cluster formation of erbium in silica and consequently enhanced the luminescence spectra. In this paper, we present study on various molar ratio of SiO2-ZrO2 doped with 0.58 mol% Er3+ prepared via sol-gel technique. Increased percent molar ratio of zirconia shows narrow sharp peak of photoluminescence spectra at 568 nm wavelength with higher intensity. It is anticipated that the refractive index increased with higher zirconia content while the coating tends to form thinner film layers. The surface roughness and optical transmission of the samples are also presented.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115311027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The laser cavities; unidirectional and bidirectional are tested under the same experimental conditions using different SMF lengths.

Moreover, the maximum power of the first and the second Stokes signals are tested using different SMF length for both cavities.
