High-frequency small-signal modulation characteristics of short-cavity InGaAsP lasers
Abstract
Measured small-signal frequency-response characteristics of directly modulated long-cavity and short-cavity InGaAsP double-channel buried-heterostructure (DCBH) lasers are reported. Relaxation oscillation resonance frequencies as high as 9.4 GHz at a bias current of twice threshold have been obtained with short-cavity devices.
