High-frequency small-signal modulation characteristics of short- cavity InGaAsP Lasers.
01 January 1984
Measured small-signal frequency response characteristics of directly modulated long-cavity and short-cavity InGaAsP double- channel planar buried heterostructure (DCPBH) 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.
