Abstract
Vertical-cavity surface-emitting laser (VCSEL) emitting at 650 nm are promising candidates as transmitter in optical data communication systems based on polymer optical fibres (POF) because of a narrow minimum in transmission loss of POF at this wavelength. So far, small-signal resonance frequencies fr have been reported for 670 nm devices of 7 GHz [1] and for 656 nm VCSEL of 3.75 GHz [2], respectively. In this paper we discuss theoretically and experimentally the influence of heat dissipation on the modulation behaviour of red 650 nm VCSEL.
