TTM exhibits bidirectional multi-band polarization-dependent characteristic by applying a directcurrent (dc) bias voltage on device. The chain-link SRRs of TTM can be heated up the surrounding temperature to tune the corresponding resonance. The tuning range is 0.027 THz from 0.318 THz to 0.291 THz on the bias of 0.60 V to 1.32 V. By reconfiguring the gap between chain-link SRRs of TTM, there are single-resonance with red-shift at TE mode, and multiresonance with blue-shift and red-shift at TM mode, respectively. These characterizations of TTM are polarization-dependence and bidirectional tunability. These results show the electromagnetic responses of proposed TTM device is suitable for the uses for resonator, filter, switch, and sensor in the THz frequency range.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124817405","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}

Efficient light coupling between a silicon-based PIC with grating couplers and a standard single-mode optical fiber parallel with the PIC chip is realized by utilizing an angle-polished silica waveguide block fabricated with mature fabrication processes. Compared to the angle-polished-fiber-based coupling scheme, the demonstrated method can significantly decrease the distance between the fiber core and the grating coupler, and thereby offers several advantages in mechanical stability and misalignment tolerances. Simulations and experimental results suggest that the proposed technique is applicable to the passive-alignment-based photonics packaging processes.","PeriodicalId":353010,"journal":{"name":"2019 International Conference on Optical MEMS and Nanophotonics (OMN)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124553589","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}
