There has been concurrent activities in the photonic component arena to find viable solutions for realizing such WDM architectures requiring multichannel transmitters and receivers. One such area where research has been focused is in array technologies. Monolithic integration has progressed sufficiently that arrays of lasers and photodetectors are being envisioned as key device components which enable novel architectures. In particular, optoelectronic integrated circuit (OEIC) photoreceiver arrays have been actively researched worldwide for such applications. Arrays of p-i-n photodetectors have been monolithically integrated with a variety of field effect transistors (FETs) and heterojunction bipolar transistors (HBTs).","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"19 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120839840","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 III-V nitrides are ideal for these applications due to their wide bandgaps, making detectors transparent to visible and infrared radiation. There have been several publications on photoconductive GaN detectors on sapphire substrates but the effects of defect density on device performance have not been investigated. In this paper we describe the operation of GaN detectors grown by MOCVD on sapphire, SiC, and thick HVPE GaN base layers and compare the device performance of the detectors on each of these substrates.","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122345164","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 configurable wavelength demultiplexer using periodic filter chains 一种使用周期滤波器链的可配置波长解复用器

Current approaches use a spectrometer to demultiplex the wavelengths and use a switch at each wavelength to select or deselect that particular wavelength at the output. In a DWDM system with N wavelengths, N number of switches at each receiver need to be employed in order to select an arbitrary wavelength using the conventional approach. Since switches are active components, this is undesirable when N is large. A better scaling can be achieved if we can arrange a series of configurable filters in a way that half of the spectral energy is filtered out when the input spectrum is passed through each successive stage of the filter. So the first stage filters out half of the spectrum. The second stage filters out another half of the spectrum that is left from the output of the first stage, etc. Optical filters are usually interferometric devices which generate periodic complementary outputs at the same time, such as a Mach-Zehnder interferometer (MZI). The filters used at different stages could be MZIs for which the periodicity is controlled by varying the optical path differences between the two arms of the MZI. To generate more square like transmission functions, a periodic cavity structure in a form similar to a one-dimensional photonic crystal may be used.","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126028320","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}

By combining WDM mux-demux and fast electro-optic switches, a fast configurable WDM add-drop filter can be obtained. This enables using WDM with TDM in a way that each TDM time slot is also wavelength multiplexed. Hence introducing a second dimension for switching in addition to the time dimension. This also alleviates the demanding requirement on TDM as the switching throughput increases. The number of channels that can be supported in a WDM/TDM hybrid switching system is the product of the number of time slots and the number of available wavelengths. We have done preliminary analysis on the system throughput. We will present implementation considerations of the above described systems, the give the comparison on the throughput and security sides.","PeriodicalId":344325,"journal":{"name":"1997 Digest of the IEEE/LEOS Summer Topical Meeting: Vertical-Cavity Lasers/Technologies for a Global Information Infrastructure/WDM Components Technology/Advanced Semiconductor Lasers and Application","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130700241","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}
