The Michelson Interferometer contains a special fiber with a germanium-doped core and pure silica inner cladding, so the interference spectrum is formed as a result of interference of the mode of the core and one of the modes of the inner cladding. The existence of inner cladding reduces the number of interacting cladding modes. When annealing the sensor for 300 min at a temperature of 600 °C, no thermal hysteresis of the interference spectrum was observed. The temperature sensitivities of the proposed sensor are 48 pm/°C in the range of 20–250 °C and 78 pm/°C in the range of 250–600 °C. But when the sensor was exposed to a constant temperature of 700 °C and above for a few hours, a shift in the wavelength of the dip of the interference spectrum is observed. This wavelength shift, which occurs even at a fixed temperature, depends on the temperature of annealing. It can be explained by a number of processes occurring in glass at high temperatures: the changing fictive temperature of the glass, diffusion of germanium oxide from the core, and formation of mechanical stresses resulting from the difference in thermal expansion coefficients of the core and cladding, and relaxation of these mechanical stresses at an elevated temperature.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this requirement, rather than assigning a fixed bandwidth to each request, services are offered based on the requested bandwidth profile, which enables a more diverse range of services to be offered and more efficient usage of spectrum resources. To accommodate the service requests with miscellaneous bandwidth profiles, including minimum, average, and maximum spectrum slot requirements, as well as holding time, two innovative techniques have been developed. These schemes ensure that the allocated bandwidth meets the minimum requirement, does not exceed the maximum, and achieves the desired average bandwidth, considering the time-weighted average of the assigned spectrum slots over the holding period. These methods also utilize probabilistic spectrum partitioning, which enforces different probabilities to contributing spectrum partitions in a certain service realization. Employing this probabilistic spectrum partitioning along with profile-based routing, improves the chance of accommodating requests and consequently reduces request blocking probability. The results indicate that our algorithms can successfully realize the requested services by achieving a blocking probability of less than 0.07 for offered loads up to 1000 erlang, in the Deutsche Telekom network topology.</div></div>","PeriodicalId":19663,"journal":{"name":"Optical Fiber Technology","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed Raman DTS system is based on incoherent optical frequency domain reflectometry with homodyne down-conversion with excitation of spontaneous Raman backscattering by an L-band laser diode and detection of the Raman anti-Stokes in the optical C-band. A 1D-CNN is employed to predict the spatially resolved temperature profile along the fiber from the obtained anti-Stokes backscatter trace only and thus, solves the problem of temperature referencing for single-channel Raman DTS systems. The network was trained on three different scenarios, consisting of uniform and non-uniform temperature profiles along the fiber in a temperature range from 0 °C to 60 °C.
