  • Optoelectric High Frequency Modulator Integrated on Silicon
    Publication number: 20080260320
    Abstract: An optoelectronic controller for regulating an optical signal. The controller includes a ridge or rib waveguide in an SOI-type substrate. The controller also includes an active zone formed by a plurality of thin layers of silicon. The layers are either N+ type doped or P+ type doped. The zone is defined between an N+ doped zone and a P+ doped zone which together form a PIN diode. The optoelectronic controller is all-silicon and operates by means of carrier desertion.
