    摘要： A waveguide polarization rotator includes a substrate having a surface and a waveguide coupled to the surface of the substrate and operable to support a light beam along a direction of beam propagation. The waveguide includes a slab having a support surface and a second surface opposing the support surface and a rib protruding from the second surface of the slab in a direction substantially normal to the surface of the substrate and extending along the direction of beam propagation. The rib includes a first portion extending to a first height above the second surface of the slab and a second portion adjacent to the first portion and extending to a second height above the second surface of the slab. The second height is less than the first height.

    摘要： Apparatus and methods for linearizing an optical transmitter are described. A linearized optical transmitter according to the present invention includes a modulator bias voltage supply that biases an optical modulator. The optical modulator modulates an optical signal with a payload modulation signal. A feedback circuit receives electrical distortion signals generated by the modulator and generates a control signal in response to at least one of the electrical distortion signals. The control signal changes the bias voltage generated by the modulator bias voltage supply so as to reduce the at least one electrical distortion signal.
