We report error free (BER <; 10-12) operation of a directly non-return-to-zero modulated 850-nm vertical cavity surface-emitting laser (VCSEL) link operating to 71 Gb/s. This is the highest error… (More)
We report a directly modulated 850nm VCSEL-based optical link operating error free (BER <; 1E-12) at 64Gb/s over 57m of OM4 multimode fiber. At 60Gb/s, the error free distance increases to 107m.
Optical fiber links have become ubiquitous for links at the metropolitan and wide area distance scales, and have become common alternatives to electrical links in local area networks and cluster… (More)
A parallel, 32-channel, high density (140 /spl mu/m pitch), 500 Mb/s NRZ, point-to-point, optical data link has been fabricated using existing GaAs IC, silicon optical bench (SiOB), and multichip… (More)
We demonstrate a 1530 nm VCSEL that can operate error-free without DSP or FEC to 56 Gb/s. At 50 Gb/s, error-free operation is attained up to 2 km of SMF. A two-tap FFE driver is used to precompensate… (More)
We demonstrate 4 × 4 and 8 × 8 switch fabrics in multistage topologies based on 2 × 2 Mach-Zehnder interferometer switching elements. These fabrics are integrated onto a single chip with digital CMOS… (More)
We design, fabricate and demonstrate 850 nm VCSEL and PD arrays which operate at 25 Gb/s per channel, up to 600 Gb/s with 24 channels, for low-power parallel optical module applications. We also… (More)
We report a directly modulated 850nm VCSEL-based Optical link operating at 55Gb/s. This is the highest modulation rate for VCSEL-based link of any wavelength.
Error free data transmission at 30 Gb/s has been demonstrated at 850 nm using a oxide AlGaAs based VCSEL with GaAs quantum wells. This is comparable to the best results for VCSELs at any wavelength.
We report here on the design, fabrication, and high-speed performance of a compact 48-channel optical transceiver module enabled by a key novel component: a “holey” Optochip. A single CMOS… (More)
