One of the advantages is to be insensitive to pointing instability of the pulsed laser because no hard aperture is employed as in the usual Z-scan. In addition, the numerical calculations involved here and the measurement of the beam radius are simplified since we do not measure the transmittance through an aperture and it is not subject to mathematical artifacts related to a normalization process, especially when the diffracted light is very low.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123900545","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}

Using an experimental setup specifically designed to isolate and assess the SHB and SDP behavior we are able to validate, with a good accuracy, a mathematical model derived from the fundamental equations of the three-level amplifier. We conclude that by selecting a pump wavelength centered at 974 nm instead of 980 nm, we can reduce the power excursions by 23 %, and that by increasing the channel spacing from 100 GHz to 150 GHz the power excursions decrease by more than 20 %. Further simulations are done to investigate the behavior of SHB and SDP in an EDFA with ideal gain control. We verify that in a subband switch, changing from the red subband to the blue subband causes higher deviations than when changing from the blue subband to the red subband of the c-band. Also, in a drop scenario, the overshoots and undershoots of the surviving channel depend on the input channels spectral allocation and on the gain of the amplifier.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115726932","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}

Considering the fact that wavelength utilization is quite low for most of the time due to the bursty nature of the traffic and the fluctuation of the bandwidth demand, we propose a novel user migration mechanism for the Time and Wavelength Division Multiplexed PON (TWDM-PON). With the proposed migration mechanism, one can minimize the active wavelength up to theoretical lower bound under typical ONU online profiles. We investigate how the user Service Level Agreement (SLA) is affected by the migration interval and migration delay. Our results show that 99.999% SLA can be guaranteed when the migration delay is less than 10 milliseconds.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115057789","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 analysis is carried on the context of a metropolitan network, since its resources are limited and the WDM/OCDM technology is becoming an interesting way to improve the utilization of wavelengths. However, the pulse broadening is also increased when using WDM/OCDM technology, since the chip rates are higher than the bit user rates due to the process of code construction, and the dispersion mechanisms must be taken into account even when modeling metropolitan optical networks, in which the route distances are much smaller than that in a core optical network.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"57 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116384590","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}

Inter-cluster communication bottleneck of current DCs tree topology causes fragmented pools of servers and high latency by employing a large port count (100s) optical packet switch (OPS) to flatten the DC network topology. However, the reconfiguration time of several OPS architectures with centralized control is port count dependent. Scaling the port count causes larger latency, and thus larger buffers for storing the packets in a flow controlled operation. We present numerical and experimental results that validate the operation of a flow-controlled optical packet switch cross-connect with distributed control and nanosecond packet switching/retransmission. Real-time operation of a random packet traffic generator with variable load, FIFO queue packet storing with buffer managers for packet retransmission, contention resolution and fast switch reconfiguration control have been implemented by using an FPGA.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"243 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122294699","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}

We also study the impact of the sizes of media files and the impact of the power efficiency of caches on the network power consumption.

We present the design of a hybrid guided-wave / free-space filtering apparatus based on high resolution Arrayed Waveguide Gratings (AWG). These hybrid systems, called photonic spectral processors (PSP), can access and manipulate the fine spectral components of a lightwave signal with a spatial light modulator. In order to achieve sub-GHz resolution of the PSP, an AWG with large number of waveguides and long incremental waveguide lengths is needed. Such an AWG require careful design in order to enable relatively compact realization with a dense waveguide count, and an additional step of phase error correction which are inevitable in such design. In this paper we review the design consideration of a high resolution AWG with 200 GHz FSR and sub-GHZ spectral resolution and describe the phase errors interferometric measurement system and the UV trimming system which is needed as an essential post production process.","PeriodicalId":376939,"journal":{"name":"2013 15th International Conference on Transparent Optical Networks (ICTON)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122988899","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}
