Abstract
The highly stable operation of 980 nm transverse coupled cavity vertical cavity surface emitting lasers (VCSELs) with enhanced modulation bandwidth for high-speed optical interconnects is reported. The device operates at 25 Gbit/s from 0 to 60°C with fixed driving conditions. In addition, the stability of driving currents into the VCSEL is explored, exhibiting that the bandwidth enhancement is not sensitive to the current. The ultra-compact inplane coupled cavity VCSEL can boost the modulation speed beyond the relaxation oscillation frequency because of the to photon-photon resonance, which makes it useful in next-generation computing and data centre networking.
