Monolithic Electro-Optically Modulated VCSEL Suitable For Radio over Fibre Applications to 20 GHz
Fiber optics communications Modulators
2011/5/25
An integrated EOM VCSELs is shown to offer high linearity (92dB/Hz ⅔ at 6GHz) and by extrapolation ~90dB/Hz ⅔ up to 20GHz. Successful modulation with IEEE 802.11g signals is demonstrated...
25-Gb/s Transmitter for Optical Interconnection with 10-Gb/s VCSEL Using Dual Peak-Tunable Pre-Emphasis
Optics in computing optical interconnects
2011/5/22
We developed a 25-Gb/s VCSEL transmitter with 10-Gb/s VCSEL. By driving standard 10-Gb/s VCSELs using pre-emphasis technology to overcome their optical bandwidth limit, we achieved clear eye opening a...
