It is shown quantitatively how better optical coupling improves the photoresponse of the MESFET. It is pointed out that by modest redesign its frequency response can be significantly extended up to 10 GHz. How these can be converted to better optical control of MMIC circuits is demonstrated. A direct optical injection locking of a MESFET oscillator was performed. The measured optical injection locking bandwidth was 43.8 MHz.<<ETX>>","PeriodicalId":263441,"journal":{"name":"1991 IEEE MTT-S International Microwave Symposium Digest","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122057213","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}

First, the electric field in the dielectric ridge is expressed in terms of a polarization current from which an equivalent surface current density is defined. Further, generalized boundary conditions are enforced in order to provide a simple integral equation. Results derived by this modified integral equation approach give excellent agreement with other numerical methods. The main advantage of this technique is that it simplifies greatly the analysis of three-dimensional complex structures.<<ETX>>","PeriodicalId":263441,"journal":{"name":"1991 IEEE MTT-S International Microwave Symposium Digest","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128339141","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}

Reinforced by the 25X model results, a working V-band probe was constructed with bias capability. This probe performed well, and measurements could be easily corrected.

By eliminating the use of relatively thick high-dielectric substrates, a bandwidth of 3:1 and a differential phase of 50 degrees /cm are feasible. The addition of thin layers of high-dielectric material is shown to increase the differential phase to over 100 degrees /cm without significantly reducing the bandwidth.<<ETX>>","PeriodicalId":263441,"journal":{"name":"1991 IEEE MTT-S International Microwave Symposium Digest","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128007971","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}
