摘要： Disclosed is a wavelength division multiplexer/demultiplexer having a grating for demultiplexing a multiplexed optical signal, an input waveguide and an output waveguides. The input waveguide comprises a first sub-waveguide having a width that gradually increases in a progressing direction of the optical signal and a second sub-waveguide having a width that gradually decreases in the progressing direction of the optical signal passing through the first sub-waveguide. Since the inputted optical signal within the increased portion of the input waveguide has an expended bandwidth and the inputted optical signal within the decreased portion of the input waveguide has a reduced side lobe, an interference effect is prevented, which may be generated between neighboring channels, and improves quality of the optical signal transmitted and received in a wavelength division multiplexed (WDM) optical communication network.

摘要： Head stack assembly coupling at least two micro-actuators sharing lateral control signal. Any two adjacent micro-actuators respond to lateral control signal by opposite lateral directions. With pairs of micro-actuators, lateral motion of the micro-actuators will be cancelled, essentially leaving head stack assembly without induced torque. With odd numbers of micro-actuators, head stack assembly will effectively experience only lateral motion of one micro-actuator, minimizing induced torque. The micro-actuators may use electrostatic effect and/or piezoelectric effect to create lateral motion. The micro-actuators may further include a vertical actuation capability, which may preferably be independent of the lateral control signal. The servo controller operates based upon micro-actuator being used. Embedded circuit includes servo controller. The hard disk drive containing head stack assembly and further containing servo controller. Manufacturing hard disk drive and head stack assembly. The head stack assembly and hard disk drive, as products of these manufacturing processes.
