Additionally, a method to select aliasing-free bandpass sampling frequency is derived. This method is suitable for subcarrier multiplexing (SCM) scenario with the presence of independent free-running optical local oscillator (LO) caused frequency offset. Analytical assessment and simulations are used to determine the ultimate performance with respect to ADC bits resolution and laser linewidth. The simulation result shows that 8 bit resolution and narrow laser linewidth (less than 100kHz) are expected to achieve high performance link for undersampling applications in the PM-CD RoF links.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122034692","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}

In this approach, we realized DCS of OFDM subcarriers in single polarization (or channel), denoted as SP-DCS-OFDM. In this paper, we show that another approach is in dual polarizations, or DP-DCS-OFDM. We prove that both approaches can reduce the ICI due to phase noise, including laser phase noise and nonlinear phase noise. We discuss their improved phase noise tolerance in simulation. We also discuss their difference in terms of complexity and performance.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131078068","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}

This MOSFET was capable of driving the TO phase shifter because of its large current capability. By tuning the gate voltage of the MOSFET, the switching state of MZS was successfully controlled. We will also present our work on the robust switch design with the intention to minimize the negative influences on switching performance due to so many MOSFET process steps. For this purpose, we had proposed a new 3dB directional coupler which was more robust to the gap variation than the conventional one. Our monolithic MOSFET is promising in simplifying the driver circuits and in developing on-chip drivers for TO-based silicon photonics devices.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131119707","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}

Since the linear and nonlinear phase noise is transferred with the data to the converted wavelength in AOWC subsystem, it is imperative to optimize the operation condition in AOWC to suppress noise to allow compatibility phase-noise sensitive high-order QAM formats. We first investigate the performance optimization of AOWC for high-order QAMs like 64QAM through four-wave mixing in highly nonlinear fiber, and then discuss our proposed AOWCs schemes for high-order QAM signals such as 16/64-QAM using coherent pumps which is free of phase noise from pumps.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116293526","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}
