Devices based on semiconductor multiple quantum wells are of particular interest because of the possibility of combining modulators with detectors and electronic components on a single substrate to make high-speed smart-pixel arrays. However, it is difficult to obtain large contrast ratios in conventional MQW modulators, which function by using the quantum confined Stark effect to modify the absorption coefficient of the MQW. For example, a typical p-i(MQW)-n modulator has a contrast ratio of 3:1 to 5:1, although contrast ratios as high as 10:1 have been obtained. Fabry-Perot cavities have been used to increase the contrast ratio to 100:1, but at the expense of optical bandwidth.","PeriodicalId":188204,"journal":{"name":"Spatial Light Modulators and Applications","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126816307","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}

These include \"smart pixel\" digital processors,1 as well as image processors that employ spatial light modulators. These modulators are typically pi( MQW)-n diodes, grown by techniques such as Molecular Beam Epitaxy (MBE), wherein an integral multilayer mirror is produced underneath the MQW. By reverse biasing the diode the MQW’s absorption is modified and hence the reflectivity of the device is modulated. In simple designs a perfect anti-reflection coating is placed on the surface so multiple reflections do not occur within the modulator. This has the advantage that no strict control of the overall thickness of the device is required.","PeriodicalId":188204,"journal":{"name":"Spatial Light Modulators and Applications","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133517151","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 concept is to use a Schottky metal-semiconductor interface which allows depletion through the silicon to be attained and thus maintain the impedance match between the photoconductor and the liquid crystal. This match is critical in achieving the operation of a photoactivated SLM.(1) Since a high Schottky barrier-forming metal such as aluminum or platinum can be deposited on the n-type silicon substrate at low temperature, the silicon substrate can first be mounted on a flat glass substrate, polished, and then processed. This allows a high degree of output uniformity to be attained. Secondly, by eliminating the SiO2 insulator present in our MOS LCLV version,(2) one can reduce the sheet conductivity at the Si/LC interface and achieve higher resolution and dynamic range.","PeriodicalId":188204,"journal":{"name":"Spatial Light Modulators and Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125012526","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}

As a consequence of the deposited charge image, the fluid surface is deformed by electrostatic stresses. For the incident light, this surface deformation represents a phase object causing phase modulation and thus diffraction. The conversion of this (invisible) phase modulation into a (visible) intensity modulation is achieved by means of a schlieren-optical imaging system. In previous publications [1,2], the transfer characteristics of the system for sinusoidal charge patterns, which lead to sinusoidal deformations because of the control-layer's linear transfer function, were extensively described; here, the transfer characteristics of the same system for spatially non-periodic structures are analyzed, and the resolution limits caused by the incompressibility of the SIM material and by the optical filtering are determined.","PeriodicalId":188204,"journal":{"name":"Spatial Light Modulators and Applications","volume":"25 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":"125026196","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}
