Demonstration of 10.7-Gb/s transmission in 50-km PON with uncooled free-running 1550-nm VCSEL

First-known demonstration of an uncooled, free-running 1550 nm VCSEL at 10.7 Gb/s over 50 km PON uplink with 35 km SMF and 15 km inverse dispersion fiber, achieving 24 dB margin for 10−9 BER

All-optical delay technique for supporting multiple antennas in a hybrid optical - wireless transmission system

We introduce a novel continuously-variable optical delay technique to support beam-forming wireless communications systems using antenna arrays. We demonstrate delay with 64-QAM modulated signals at a rate of 15 Msymbol/sec with 2.5 GHz carrier frequency

Free-running L-band VCSEL for 1.25 Gbps hybrid radio-fiber cloud optical interconnects

International audienceWe demonstrate a free-running directly-modulated 1580 nm VCSEL suitable for hybrid wireless/optical interconnects supporting cloud data centers. Error-free transmission at 1.25 Gbps was achieved after 6.5 GHz wireless link and 1 km bend-insensitive fiber

Converged wireline and wireless access over a 78-km deployed fiber long-reach WDM PON

In this letter, we demonstrate a 78.8-km wavelength-division-multiplexing passive optical network supporting converged transport of 21.4-Gb/s nonreturn-to-zero differential quadrature phase-shift keying, optical phase-modulated 5-GHz radio-over-fiber, fiber and air transmission of 3.125-Gb/s pulse ultrawideband, and 256-quadratic-amplitude modulation wireless interoperability for microwave access

Free-Running 1550 nm VCSEL for 10.7 Gb/s Transmission in 99.7 km PON

We present a cooler-less, free-running 1550 nm vertical cavity surface emitting laser (VCSEL) directly modulated at 10.7 Gb/s. We also report on error-free transmission through 40 km of standard single-mode optical fiber, achieved without the use of dispersion-mitigation or mid-span amplification. Inverse-dispersion fiber was utilized to realize a dispersion-matched 99.7 km optical access uplink supporting error-free transmission with 27 dB loss margin. These results indicate the feasibility of implementing cooler-less long-wavelength VCSEL devices in long-reach optical access networks
