The enhanced tensile strain shrinks Ge bandgap which leads to extension of optical absorption edge towards longer wavelength. It was found that 1GPa tensile SiN (400nm) would introduce ∼0.65% uniaxial tensile strain (along WG width direction) in Ge WG with 0.5μm width and extend the Γ-valley-light-hole absorption edge to ∼1658nm. Tensile strain-enhanced Ge WG-OI was also experimentally demonstrated. These studies pave the way for an on-chip tensile-strained Ge photodetector with improved performance comparable to InGaAs-based detectors. This technique is completely CMOS-compatible and could also be applied to other Ge-based on-chip active device design such as lasers.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"68 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82191882","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}

There are two pairs of FBGs with different Bragg wavelength in this system. Each pair of FBGs has a long FBG (LFBG) and a short FBG (SFBG), which have an appropriate matching operating point and determine one potential lasing line. Two pairs of FBGs are used as both the comb filter and the ultrasonic sensors. Due to the different spectral response of the LFBG and SFBG to ultrasound, the cavity loss will change regularly by the ultrasound, and the intensity of the laser output will be modulated by the cavity loss. Meanwhile, an adjustable attenuator is added to the fiber ring cavity. By adjusting the attenuator, the gain and loss of the two specific wavelengths can be balanced, and the laser oscillation at two specific wavelengths is stabled. With the modulation of the adjustable attenuator, multiplexing ultrasonic EFRL sensors can be achieved within a single cavity fiber laser. The proposed method has been experimentally demonstrated by using a dual-channel laser system with a single section of gain medium, EDF.","PeriodicalId":6655,"journal":{"name":"2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR)","volume":"35 4 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82796326","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}
