Measured characteristics at of an 850 nm VCSEL with a oxide-aperture diameter.
Small-signal modulation response of a aperture VCSEL at 25 and and the currents used for data transmission experiments (a). Extracted -factor and -factor of a aperture VCSEL (b).
BER vs received power for a aperture VCSEL at (a) 17 Gb/s and (b) 25 Gb/s both in the BTB-configuration and across 100 m of MMF at with optical eye diagrams as insets.
BER vs received power for a aperture diameter VCSEL at 17 Gb/s at in a BTB-configuration and across 100 m of MMF. A record low energy-to-data ratio of 81 fJ/bit is achieved.
State-of-the-art of energy-efficient high-speed VCSEL.
