This method makes the number of silent subcarriers as an extra modulation dimension, so as to increase the number of bits carried on SIM-OFDM symbol and improve the spectrum efficiency of the system. According to the simulation result, although the BER of multidimensional modulated GSIM-OFDM system is a little higher than that of traditional GSIM-OFDM system, the spectrum efficiency of the system with the proposed method is also better than that of the system with traditional grouped modulation method. What's more, the more groups, the more obvious the advantage of spectrum efficiency.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78300632","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 propose a novel optical delay line structure based on multimode conversion. The silicon multi-mode converter is optimized via an inverse design method to simultaneously convert the $mathbf{TEi}$ modes to $mathbf{TE}_{mathrm{i}}+1$ modes $(mathbf{i}=1,2$, and 3) at the wavelength of 1550 nm. It only occupies an area of 4 $mu mathbf{m}times 3 mumathbf{m}$. Simulation results show that the insertion loss of the mode-order converter is less than 1.6 dB and the crosstalk is lower than −22 dB for all three modes.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79842472","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}
