Lossless InAsP/InGaP modulator at 1.3 /spl mu/m for optical conversion of radio signals up to 40 GHz

An InAsP-InGaP electroabsorption modulator at 1.3 /spl mu/m integrated with a semiconductor amplifier exhibits a 10 fibre-to-fibre insertion gain, 36 GHz bandwidth and 3 V drive voltage. A RF link efficiency of -26 dB at 20 GHz was demonstrated without any external amplification.
