The thermo-optic effect in PIN waveguide will degrade the performance of the external cavity. We propose optimization strategy to avoid such effect and verified by experiment. Finally, we measured the switching speed of tunable micro-ring within 5ns.","PeriodicalId":178563,"journal":{"name":"Optoelectronic Devices and Integration X","volume":"24 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120848457","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 kernel of the proposed scheme is that injection locking technique is employed to obtain a high side-mode suppression ratio, while the delay-matched frequency conversion filtering process is used to eliminate the phase noise influence of the local oscillation (LO) signal. In the proof-of-concept experiment, a single-mode oscillation at 10 GHz is realized, where the frequency of the LO signal was set to be 10.07 GHz and an intermediate frequency bandpass filter with a center frequency of 70 MHz and a 3-dB bandwidth of 50 kHz is employed. The side-mode suppression ratio and the phase noise are measured to be 76 dB and -123.5dBc/Hz@10kHz, respectively.","PeriodicalId":178563,"journal":{"name":"Optoelectronic Devices and Integration X","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121616442","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}
