Abstract

The modulation characteristics of GaInAsP diode lasers grown on p-type substrates have been studied on devices in which the parasitic bonding pads have been eliminated. The lasers have thresholds as low as 4.5 mA. The small-signal sinusoidal response is comparable to similar lasers made on n-type substrates. A small-signal -3 dB frequency as high as 16.4 GHz has been measured with a 175-μm-long laser.
