    Abstract: A higher order mode generator is for converting the 0th order fundamental guiding mode into higher modes higher than the 0th order in a waveguide. The waveguide is made from thermo-optic materials in which the refractive index is changed according to the applied electrical power. The waveguide has at least two guiding modes and a straight heater or a linear electrode to invoke refractive index perturbation due to temperature or electric field, respectively while is laid across the waveguide at a certain tilt angle null with respect to the waveguide. When there is no external electric power applied to the heater, the 0th order single mode light of the waveguide will be propagated through the waveguide without any conversion into higher order modes. When electric current flows through the heater, however, the refractive index of the waveguide beneath the heater either gets lower (polymer) or higher (silica). Therefore, part of the light propagating beneath the heater is reflected at the heater. If the propagation angle of the reflected light is at least larger than the propagation angle of the first order guiding mode of the higher order mode generator, higher order modes will be excited by external control.

    Abstract translation: 高阶模式发生器用于将0阶基本引导模式转换成高于波导中的0级的更高模式。 波导由其中折射率根据所施加的电功率而改变的热光材料制成。 波导具有至少两个引导模式和直线加热器或线性电极，以分别在相对于波导以一定倾斜角α跨过波导穿过波导时调节由于温度或电场引起的折射率扰动。 当加热器没有外部电源时，波导的0阶单模光将通过波导传播，而不会转换成高阶模式。 然而，当电流流过加热器时，加热器下面的波导的折射率变得较低（聚合物）或更高（二氧化硅）。 因此，加热器下面传播的一部分光在加热器处被反射。 如果反射光的传播角度至少大于高阶模式发生器的一阶引导模式的传播角度，则通过外部控制激发高阶模式。

    Abstract: A novel device and method of beam steering for semiconductor lasers or optical amplifiers is disclosed. The method of the present invention achieves high signal extinction ratios, high speed, low chirp modulation by biasing a multi-lateral mode beam steering section. The device of the present invention comprises an active single vertical and lateral mode optical waveguide, a multi-lateral mode waveguide, and a mode converter. The mode converter efficiently couples output from an active single mode waveguide to two or more modes of a multi-lateral mode waveguide. Two guided modes arrive at a device facet with a particular intermodal phase difference based on initial mode phasing, multi-lateral mode waveguide length and modal dispersion properties, and facet angle. Beam steering is achieved through carrier antiguiding effect by injecting current into the multi-lateral mode waveguide from the mode converter thus changing the intermodal dispersion. Changing the intermodal phase difference changes the direction of beam propagation relative to the device facet, providing enhanced beam steering.
