Abstract :
Summary form only given.Analog applications of VCSELs require highly linear wideband operation, minimal intermodulation distortion, and high dynamic range. The maximum spur-free dynamic range (SFDR) obtained for a VCSEL is 104.3 dB Hz/sup 2/3/ at 102 MHz; error-free analog transmission over 3 km of fiber has been demonstrated at 1 GHz. This work suggests that, with future design improvements, VCSELs may be able to compete with DFB lasers for analog applications. The device used in this study is a VCSEL with an independently biased, voltage-controlled, intracavity absorber.
