    摘要: An asymmetric twin waveguide (ATG) structure with quantum-well intermixing in the taper region of the active waveguide is disclosed. The structure comprises a first waveguide, a second waveguide, and a taper formed in the second waveguide. The taper has an intermixed area formed therein comprising a plurality of quantum wells intermixed with a plurality of barriers. The quantum wells and barriers may be intermixed using plasma-enhanced intermixing such as, for example, Argon plasma enhanced intermixing. Quantum-well intermixing reduces absorption loss normally encountered in the movement of light between waveguides.

    摘要: A semiconductor photodetector may provide charge carrier avalanche multiplication at high field regions of a semiconductor material layer. A semiconductor current amplifier may provide current amplification by impact ionization near a high field region. A plurality of metal electrodes are formed on a surface of a semiconductor material layer and electrically biased to produce a non-uniform high electric field in which the high electric field strength accelerates avalanche electron-hole pair generation, which is employed as an effective avalanche multiplication photodetection mechanism or as an avalanche impact ionization current amplification mechanism.
