InGaAs quantum-well-based vertical-cavity surface-emitting lasers (VCSEL's)
at 935-nm emission wavelength are investigated for perfluorinated graded-i
ndex plastic-optical fiber (GI-POF) links. We report a 7-Gb/s pseudorandom
bit sequence (PRBS) nonreturn-to-zero (NRZ) data transmission over 80-m-lon
g 155-mu m-diameter GI-POF at a bit-error rate (BER) of better than 10(-11)
.
