Abstract :
The electrorefractive effect in a pin multiple-quantum-well (MQW) modulator has been used in a novel, electronically tuned, external-cavity GaAs/AlGaAs laser system. Mode selection over a frequency range of 600 GHz (1.4 nm change in wavelength) has been demonstrated for a 6 V change in MQW modulator bias, with less than 0.6 dB variation in laser output power.
