N.J. Frigo,Patrick P. Iannone,P.D. Magill,Thomas E. Darcie,M. M. Downs,B. N. Desai,Uziel Koren,Thomas L. Koch,C. Dragone,Herman M. Presby,G.E. Bodeep +10 more
TL;DR: In this paper, a passive optical network (PON) based on a wavelength division multiplexing router, with modulators (instead of lasers) at the subscriber terminals, is demonstrated.
Journal ArticleDOI
Semiconductor lasers for coherent optical fiber communications
Thomas L. Koch,Uziel Koren +1 more
TL;DR: The current status of semiconductor lasers used in coherent optical fiber communications is reviewed for nonexperts in the field in this article, where the issues of spectral purity, tuning, modulation, and advanced fabrication methods for photonic integration are discussed, with examples drawn from current experimental devices.
Journal ArticleDOI
A wideband all-optical WDM network
Ivan P. Kaminow,Christopher Richard Doerr,C. Dragone,Thomas L. Koch,Uziel Koren,Adel A. M. Saleh,Alan Joseph Kirby,C. M. Ozveren,B. Schofield,R.E. Thomas,Richard A. Barry,D.M. Castagnozzi,Vincent W. S. Chan,B. R. Hemenway,Douglas Marquis,Salil A. Parikh,Mark L. Stevens,Eric A. Swanson,S.G. Finn,Robert G. Gallager +19 more
TL;DR: The architecture addresses all-optical transport over the wide, metropolitan, and local areas and utilizes wavelength partitioning, routing, and active multiwavelength cross-connect switches to achieve a network that is scaleable in the number of users, data rates, and geographic span.
Journal ArticleDOI
Tapered waveguide InGaAs/InGaAsP multiple-quantum-well lasers
Thomas L. Koch,Uziel Koren,Gadi Eisenstein,M.G. Young,M. Oron,Clinton Randy Giles,Barry Miller +6 more
TL;DR: In this paper, the use of ultrathin etch-stop techniques to expand the vertical optical mode size adiabatically in 1.5-mu m InGaAs/InGaAsP MQW lasers using a tapered-core passive intracavity waveguide structure is discussed.
