Abstract
12.5Gbps operation of low-k benzocyclobutene (BCB)-planarized 850nm AlGaAs-based VCSEL is presented. The chip capacitance is 70% reduced from that of conventional SiN-passivated one. The VCSEL exhibits very high relaxation oscillation frequency of 12GHz with stable operation at 70oC over 750 hours.
