The optical design is shown of a VCSEL-based bi-directional optical interconnect system that has recently been implemented This clustered optical system transmits 256 channels in each direction and is based on a diffractive double minilens relay. The relay lenses have a square aperture of 750 /spl mu/m, a focal length of 8.5 mm, 256 phase levels and operate at a wavelength of 850 nm. Each lens relays a 4 /spl times/ 4 spot array on a 125 /spl mu/m pitch. This system was originally designed using scalar diffraction theory and so it was assumed that the diffraction efficiency is a function only of the number of phase levels in the lenses and is thus identical for all beams in the array. However since each beam within the 4 /spl times/ 4 array passes through a different set of zones in the lenses and since the outer zones of the lenses have smaller local periods than the central zones the diffraction efficiency experienced by each beam will not be identical, leading to transmission non-uniformity. In this paper we will apply rigorous coupled wave analysis (RCWA) to this optical system design in order to accurately determine the efficiency of the minilens as a function of the zone radius and hence calculate the variation in transmission efficiency that will result. We will also extend this analysis to faster diffractive optical systems (f/3.7) that relay larger (16 /spl times/ 16) spot arrays and investigate polarization dependence.","PeriodicalId":423869,"journal":{"name":"The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125201748","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}

One could use parametric amplifiers, which use four-wave mixing (FWM) to amplify the signals. Not only can parametric amplifiers provide broad-bandwidth, low-noise amplification at arbitrary wavelengths, they can also conjugate the signals and convert their wavelengths. For most signal frequencies the dominant FWM process is phase conjugation (PC), in which two pump photons, one from each pump wave, combine to produce one signal photon (s) and one idler photon (i). By tuning the pump frequencies judiciously, one can produce uniform gain over a practical bandwidth. However, the signal gain associated with parallel pump waves depends sensitively on the polarization of the input signal. Because transmission fibers are not polarization-maintaining, practical amplifiers must operate on signals with arbitrary polarizations. The properties of PC in such fibers should be intermediate between those of PC driven by parallel pumps, which was discussed in previous papers, and PC driven by orthogonal pumps, which is discussed in this paper.","PeriodicalId":423869,"journal":{"name":"The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133466703","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}
