A critical aspect of PIC-based systems is the ability to transmit optical signals between chips, which requires a low-loss, robust interface between the PIC-chip and optical fiber. Here we present a thorough examination of a fiber fusion attachment process to create such an interface. The process used a CO2 laser to heat and fuse the fiber to a silicon nitride chip and achieved a measured coupling loss of ~2.45 dB/facet for 1550 nm light, which represents a reduction in loss of 0.5dB/facet from prior to the fusion splice being formed. A force sensor was integrated into the fusion splicing process to allow for quantitative analysis of splicing conditions. Additionally, the robustness of the fusion splicing process was demonstrated by repeated temperature cycling of a spliced chip between 193 K and 293 K led to an increase in loss of only 0.3 dB after five cycles.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, on-chip silicon polarizers are still difficult to balance the compact size and superior performance. In order to break the above problems, an inverse design method is exploited to achieve ultra-compact silicon transverse electrical (TE)-pass polarizers. Compared with the reported polarizers (tens of micrometers), the 5.43-\u0000<inline-formula> <tex-math>$mu $ </tex-math></inline-formula>\u0000m-length of the proposed polarizer is significantly reduced by an order of magnitude. More importantly, the minimum insertion loss is as low as 0.17 dB and the experimental operation bandwidth could realize 100 nm (1500 nm~1600 nm). Furthermore, the maximum value of the extinction ratios could realize up to 32.2 dB. To the best of our knowledge, it is the first time to realize silicon optical polarizers with a record ultra-short length of \u0000<inline-formula> <tex-math>$5.43~mu $ </tex-math></inline-formula>\u0000m, ultra-low insertion loss of 0.17 dB and wide bandwidth of 100 nm based on the inverse design method.

In most experiments, the etalon is generally regarded as an ideal optical device. However, if there is any loss in the FP etalon, its parameters including transmittance, linewidth, and finesse will be affected, which will in turn affect the experimental results. In this letter, we propose an estimation method for surface and medium losses of FP etalon. When the FP etalon is not filled with any medium, we establish a relationship between the peak transmittance of the etalon and the surface loss through theoretical calculations. When the FP etalon is filled with a medium, we derive a relationship between the peak transmittance of the etalon and both the surface and the medium loss through calculations. The two functional relationships we established provide a theoretical foundation for experimental measurements of the surface and medium loss of the FP etalon. Based on these functional relationships, we propose a method for estimating the surface and medium losses of FP etalon. Our loss estimation method is also applicable to the FP interferometer.","PeriodicalId":13065,"journal":{"name":"IEEE Photonics Technology Letters","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
