We review the electroabsorption (EA) device as a linear mixer for frequency conversion. We explain the operating principle and compare the operation of the EA device as a modulator/mixer with the operation as a detector/mixer. We present experimental results of EA devices with the quantum- confined Stark effect and the Franz-Keldysh effect. Using a InAsP/GaInP multiple-quantum-well EA device, a conversion loss of 18.4 dB is obtained at 10-mW optical local oscillator power when the device is operated as a detector/mixer. The two-tone measurement on the same device shows a sub-octave, spur-free dynamic range of 120.0 dB-Hz. Phase noise measurement demonstrates that very low phase noise is added in the conversion process. We propose a novel full-duplex operation of the EA device as a detector/mixer for the application in the antenna remoting or fiber-radio systems. |
