TL;DR: The first sub-100nm technology that allows the monolithic integration of optical modulators and germanium photodetectors as features into a current 90nm base high-performance logic technology node is demonstrated.
Journal ArticleDOI
Methane absorption spectroscopy on a silicon photonic chip
TL;DR: In this paper, the evanescent optical field of a high-index contrast nanoscale silicon waveguide is used to probe ambient CH4, yielding Gaussian noise-limited sub-100 parts-per-million by volume detection limits.
Journal ArticleDOI
A Novel Approach to Photonic Packaging Leveraging Existing High-Throughput Microelectronic Facilities
Tymon Barwicz,Yoichi Taira,Ted Lichoulas,Nicolas Boyer,Yves Martin,Hidetoshi Numata,Jae-Woong Nah,Shotaro Takenobu,Alexander Janta-Polczynski,Eddie Kimbrell,Robert K. Leidy,Marwan H. Khater,Swetha Kamlapurkar,Sebastian Engelmann,Yurii A. Vlasov,Paul Fortier +15 more
TL;DR: Two approaches to fiber-to-chip interfacing and one to hybrid photonic integration involving direct flip-chip assembly of photonic dies are demonstrated, meant to be universal by simultaneously allowing wide spectral bandwidth for coarse wavelength division multiplexing and large optical-port count.
Journal ArticleDOI
Demonstration of a High Extinction Ratio Monolithic CMOS Integrated Nanophotonic Transmitter and 16 Gb/s Optical Link
Douglas M. Gill,Jonathan E. Proesel,Chi Xiong,Jason S. Orcutt,Jessie Rosenberg,Marwan H. Khater,Tymon Barwicz,Solomon Assefa,Steven M. Shank,Carol Reinholm,John J. Ellis-Monaghan,Edward W. Kiewra,Swetha Kamlapurkar,Chris Breslin,William M. J. Green,Wilfried Haensch,Yurii A. Vlasov +16 more
TL;DR: In this paper, a 16-Gb/s LiNbO3 transmitter with a stacked voltage-mode CMOS driver and a reverse biased pn junction Mach-Zehnder modulator is presented.
Journal ArticleDOI
Automated, high-throughput photonic packaging
Tymon Barwicz,Ted Lichoulas,Yoichi Taira,Yves Martin,Shotaro Takenobu,Alexander Janta-Polczynski,Hidetoshi Numata,Eddie Kimbrell,Jae-Woong Nah,Bo Peng,Darrell Childers,Robert K. Leidy,Marwan H. Khater,Swetha Kamlapurkar,Elaine Cyr,Sebastian Engelmann,Paul Fortier,Nicolas Boyer +17 more
TL;DR: Self-alignment structures and large-mode converters are integrated on chip to enable photonic packaging in standard, automated, high-throughput microelectronic assembly tools and it is believed this new direction can help silicon photonics reach its full potential.
