摘要

We demonstrate generation of gigahertz to terahertz optical subcarrier radio frequencies in semiconductor optical amplifiers. The circuit arrangement consists of a laser diode driven below its lasing threshold to generate spontaneous emission spectrum. The spontaneous emissions are passed in a saturation driven semiconductor optical amplifier with low-end-reflectivity. A fraction of the output signal emerging from the amplifier is fed back into the input of the amplifier. By appropriately arranging the phases of the input and the feedback signals, beat frequencies up to 3.75 THz were generated.
