Abstract: Disclosed herein are methods, structures, and devices that compensates for modulator loss and modulation inefficiencies introduced by mask misalignments in opposite oriented pn type junction modulators. More specifically, Mach-Zehnder type optical modulators are disclosed wherein both arms in the MZI modulator are arranged in a push-pull configuration and configured to experience pn type junctions of two orientations wherein both arms further configured to experience the same length of waveguide with a pn type junction of each orientation.

Abstract: Aspects of the present disclosure are directed to a multi-section mismatched modulator. In one embodiment, a segmented bias electrode is provided along the length of the optical waveguide in the optical modulator. Each segmented bias electrode may have a pre-determined bias voltage that can reduce impedance mismatches along the length of the signal electrode to reduce echoes and ripples in the modulation signal. In an embodiment implemented as a P-I-N diode modulator, the bias electrode is used to apply a reverse bias transversely to the section of the diode modulator between the bias electrode and the signal electrode. According to an aspect, RF impedance along the length of the signal electrode can be tuned by adjusting the magnitude of the reverse-bias point at different segments of the bias electrode, and be matched to a desirable impedance value to reduce reflection and ripple effects.

Abstract: A method for steering a beam is disclosed. According to the method, a scene is scanned with a surface emitting grating optically coupled to a free propagation region. The free propagation region is optically coupled to waveguides. The waveguides are disposed at different angles to the surface emitting grating. The scanning includes scanning in a first dimension by cycling through a cross connect to illuminate each waveguide of the waveguides. Scanning in a second dimension is performed by tuning a wavelength of light used to illuminate the waveguides.
