Abstract
Relaxation oscillation frequencies are reported for short cavity GaAs/AlGaAs multiquantum well lasers with dry-etched facets. Decreased electron and photon lifetimes combined with the high differential gain constant of short cavity lasers yield very high relaxation oscillation frequencies. A peak value of 24 GHz was achieved with a 40-μm-long laser, and a linear relationship between frequency and the square root of the output power is observed.Keywords
