Abstract
Disclosed are systems and methods for using a semiconductor optical amplifier (SOA) as an optical modulator for pulsed signals. In accordance with the principles of the invention, the SOA can be biased with a negative voltage to suppress transmission and improve modulator extinction and biased with a positive pulsed signal with sufficient amplitude to forward bias the amplifier (SOA), both transmitting the carrier and increasing its amplitude by means of a gain provided by the SOA under forward biased conditions. In addition, the forward bias voltage may be selected to compensate for losses within the SOA.
