Electric control of pulse reshaping using an intracavity silicon waveguide

Electric control of the pulse reshaping and compression is demonstrated using the two-photon absorption (TPA) and TPA-induced free-carrier absorption in an intracavity silicon waveguide. A forward bias is applied to the silicon waveguide to tune the free-carrier lifetime and density, hence enhancing the pulse compression effect. A pulse compression of about 30% is experimentally verified using a 3.3 V forward bias.
