Research

   We demonstrate the generation of terahertz optical subcarrier radio frequencies in a semiconductor optical amplifier. The circuit arrangement consists of a 1550 nm pigtailed laser diode driven below its lasing threshold to generate a spectrum of spontaneous emission.

   The goal is to generate modelocked laser pulses with a repetition rate of 5GHz or greater. The high repetition rate of the modelocked pulses have applications that include optical timing devices, high-speed data transmission, and ultrafast optics.
