By this optimal condition, the growth rate by Au induced can be as large as 15.9 mum/hr. Due to low annealing temperature treatment (les 400degC) and large growth rate, this novel technology will be a noticeable poly-SiGe:H pin IR-sensing fabrication on a conventional pre-coated indium tin oxide (ITO)-glass substrate. Under 1-muW IR-LED incident (with peak wavelength at 710 nm) and at 5-V biased voltage, the poly-SiGe:H pin IR sensor developed by the Au-ILC technology, i.e., an Al (anode)/n poly-SiGe:H/i poly-SiGe:H/p poly-SiGe:H/ITO (cathode)/glass-substrate structure posses a maximum optical gain and response speed, almost 600% and 130%, respectively, better than that of a traditional pin type. Meanwhile, the FWHM of a poly-SiGe:H pin sensor with Au-ILC technology corresponding to a traditional pin sensor can be reduced from 280 to 150 nm, thus ascertaining its good IR-sensing selectivity. These better IR-sensing performances are demonstrated again that the proposed Au-ILC technology is a candidate to the low cost IC on opto-electronic applications.","PeriodicalId":244615,"journal":{"name":"ACOFT/AOS 2006 - Australian Conference on Optical Fibre Technology/Australian Optical Society","volume":"27 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120822187","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 presence of air holes benefits sensing and permits the general introduction of materials for applications as diverse as switching and modulation. Of particular note are air clad fibre lasers, which are an increasingly preferred alternative to polymer clad fibre lasers for high power operation. The ability to incorporate gratings, including DFB structures, into these fibres paves the way for future all-fibre topologies where bulk optics need not be necessary. However, significant research effort remains to ensure that this potential is fulfilled. A review of the work carried out at the OFTC highlighting their properties and potential is presented.","PeriodicalId":244615,"journal":{"name":"ACOFT/AOS 2006 - Australian Conference on Optical Fibre Technology/Australian Optical Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122951751","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}
