A single semiconductor optical amplifier (SOA) placed asymmetrically in the loop acts as the non-linear element in the interferometer. Most integrated wavelength converters use the Mach-Zehnder geometry, which requires two SOAs, hence balancing the interferometer becomes an arduous task. The Sagnac geometry, on the other hand, uses a single SOA and the clockwise and the counter clockwise signals traverse the same optical path, thereby negating the effects of optical path length differences. The device is fabricated in the InGaAsP/InP material system grown by gas source molecular beam epitaxy. A tunable (1530-1560 nm) mode locked fiber laser operating at 10 Gb/s was used as the control signal and a distributed feedback (DFB) laser operating at 1540 nm was used as the continuous wave signal. Wavelength conversion observed at 1540 nm with data at 1553 nm is shown Dependence of the on/off extinction ratio on wavelength is shown clearly indicating the uniform performance over the entire C-band. Both up conversion and down conversion is demonstrated by the device.","PeriodicalId":423869,"journal":{"name":"The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121455402","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 device used for this work is a standard Fabry-Perot ridge-waveguide laser diode operating at 1.3 /spl mu/m. The active layer contains seven InGaAsP quantum wells. By positioning the grating in the ridge of the laser there is a strong interaction with the lasing mode and only a short grating length is required to dramatically alter the performance of the laser. The output spectrum of the device shows it is lasing on a single longitudinal mode at a considerably shorter wavelength than before the grating was incorporated. Additional structure is observed from the grating and the temperature dependence of the lasing mode is reduced to that expected from a distributed-feedback semiconductor laser. This shows the dominance of the grating in determining the laser characteristics. Incorporating structures into the cavity in this way may allow enhanced functionality in future devices.","PeriodicalId":423869,"journal":{"name":"The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society","volume":"560 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114340575","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}
