    摘要: The present invention is a method and an apparatus for tuning an optical delay line. In one embodiment, an optical delay line includes at least one ring resonator in which light is guided or is confined and at least one heater positioned laterally from the ring resonator. The heater produces heat in a localized area, allowing for the tuning of individual delay elements with minimal crosstalk.

    摘要: The present invention is a waveguide photodetector. In one embodiment, the waveguide photodetector includes a waveguide layer where light is guided or is confined and a detection layer formed on the waveguide layer where guided light is detected. Each of the waveguide layer and the detection layer allows for the guiding of no more than a single mode of light for a given polarization. In another embodiment, the waveguide photodetector includes a waveguide layer where light is guided or is confined, a detection layer formed on the waveguide layer where guided light is detected, a first electrical contact coupled to the detection layer, and a second electrical contact coupled to the detection layer. The first electrical contact and the second electrical contact are disposed in a spaced-apart, substantially parallel manner relative to each other.

    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.
