Extremely high-frequency (24 GHz) InGaAsP diode lasers with excellent modulation efficiency

Abstract

1.3 μm InGaAsP lasers with 3 dB bandwidths of 24 GHz and intrinsic resonance frequencies in excess of 22 GHz have been successfully fabricated. This is the highest bandwidth ever reported for a semiconductor laser, and the highest resonant frequency for InGaAsP lasers. Excellent modulation efficiencies are observed to high frequencies.
