In industry, AR coatings and filters are typically produced by using thin-film techniques. Sub wavelength structures can avoid many of the problems encountered in thin-film approaches, and be replicated at low cost. Subwavelength structures also have the potential to be combined with micro-optical elements such as lenses, gratings or kinoforms. However, previous studies have either been focused on the analysis of pure subwavelength gratings [2] or micro-optical elements coated with thin films [3].","PeriodicalId":301804,"journal":{"name":"Diffractive Optics and Micro-Optics","volume":"227 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114089058","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}

A grating coupler utilizing higher-order diffraction has much longer grating period than that of a 1st-order grating coupler, and is attractive from a view point of fabrication and design flexibility especially for a case using a short wavelength or a high guided-mode index. However, a coupling efficiency of the usual higher-order diffraction is too low to be utilized in practical applications. We reported [4] a proposal and design consideration of a high-efficiency 3rd-order grating coupler for application to a GaAs/AlGaAs waveguide. In this report, an efficiency enhancement technique for 3rd-order grating coupler is demonstrated experimentally for the first time. Wavelength of 0.82μm and a glass waveguide are used for the demonstration.","PeriodicalId":301804,"journal":{"name":"Diffractive Optics and Micro-Optics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114478166","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}

Gratings on light-weight plastic materials can replace heavy and expensive glass devices. Embossing techniques can be used for cheap mass production.

Such elements can be fabricated in the form of surface-relief profiles by a variety of methods including selective etching or material deposition, and diamond turning. Binary surface-relief elements have diffraction efficiencies of the order of 30–75% depending on the symmetries of the signal, while efficiencies even in excess of 90% are only possible if one employs continuous surface profiles fabricated, e.g., by direct-write laser beam or electron-beam lithography. Then, however, accurate exposure control is needed. Continuous surface profiles can be approximated by multilevel profiles, which may be fabricated by successive lithography steps, where careful mask alignment is then required.","PeriodicalId":301804,"journal":{"name":"Diffractive Optics and Micro-Optics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123512923","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}

We comment on the connection between transmission gratings and reflection gratings and note that many combinations of gratings and multilayer stacks offer high efficiency. Thus it is possible to attain secondary objectives in the design. We describe examples of such designs aimed toward improving fabrication and lowering the susceptibility to laser-induced damage.","PeriodicalId":301804,"journal":{"name":"Diffractive Optics and Micro-Optics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130539969","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}

Current integrated narrow-band optical filters are limited by their size, density of devices that can be produced, overall performance, and ability to be actively altered for tuning and modulation purposes. In contrast, the integrated optical filters described in this work can have extremely narrow bandwidths - on the order of a few angstroms. Also, their compact size enables multiple filters to be integrated in a single high density device for signal routing or wavelength discrimination. Manipulating any of the resonant structure’s parameters will tune the output response of the filter, which can be used for modulation or switching applications.","PeriodicalId":301804,"journal":{"name":"Diffractive Optics and Micro-Optics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122342242","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}
