摘要： Provided is a mode converter for use in optical communication. The mode converter includes a first waveguide, a second waveguide optically coupled into the first waveguide, and omnidirectional reflectors that are disposed on either side of the first waveguide and have forward reflectivity with respect to a mode propagating in the first waveguide. The mode converter provides minimum loss coupling between either optical fiber or low index difference waveguide and a high index contrast waveguide. Furthermore, the mode converter achieves high, bi-directional optical coupling over a wide wavelength range with a simple manufacturing process.

摘要： A speed control apparatus for a rotary motor includes a motor for rotating at a speed based on a torque command and which outputs a present angular position and a present angular speed of the motor. A speed measuring unit is provided for obtaining a speed error representing the difference between a reference angular speed and a present angular speed. A speed controller is provided for outputting a current command for controlling a rotational speed of the motor. A learning compensator is provided for correcting an effect of a disturbance expressed as a function of an angular position and an angular speed applied to the motor, via a repetitive learning process using the reference angular speed, any one of the speed error from the speed measuring unit and the current command output from the speed controller and the present angular position of the motor, for removing a high frequency noise generated in the repetitive learning process, and for outputting a resultant disturbance correction value. A speed command compensator is provided for obtaining a corrected current command by adding the current command value output from the speed controller and the disturbance correction value obtained in the learning compensator; and a current controller is provided for receiving the corrected current command and outputting a torque command to the motor. Thus, the apparatus stores in advance the correction value obtained in the learning compensator and effectively performs a speed control using the stored value.

摘要： A velocity control method for a rotary motor and an apparatus adopting the same estimates and corrects a disturbance applied to the rotary motor to improve a velocity control characteristic. The disturbance is expressed as a function of an angular velocity and an angular position via a simple calculation process. The velocity control apparatus includes a learning compensator for receiving a velocity command, angular position information and the output of a velocity controller and correcting an effect of the disturbance which is expressed as a function of the angular velocity and the angular position, in addition to a general velocity control loop of a rotary motor composed of a velocity controller, a current controller, a motor and a velocity measuring unit. The learning compensator stores one period of the output of the velocity controller at a steady state of the velocity control loop and obtains a correction value using the stored value and the previous output value. The correction value obtained in the learning compensator is stored in advance and velocity control is performed using the stored value.
