| 英文摘要 | A Bragg grating device (10) is provided including a semiconductive opticalwaveguide (12) with a Bragg grating structure (14) formed along its length. A firstplurality of electrodes (16) are disposed on a first surface (18) of the optical waveguide (12)and individually communicate with select members of the Bragg grating structure (14). Asecond plurality of electrodes (20) are disposed on a second surface (22) of the opticalwaveguide (12) and individually communicate with select members of the Bragg gratingstructure (14) such that individual electrodes of the second plurality of electrodes (20) areelectrically coupled to individual electrodes of the first plurality of electrodes (16) via theBragg grating structure (14). As such, a plurality of addressable portions (30) of the Bragggrating device (6) are defined. A plurality of electrical leads (32) are electrically coupledbetween individual electrodes of the second plurality of electrodes (20) and a power source(38) such that a refractive index of each portion (30) along the Bragg grating structure (14)may be selectively varied along the length of the optical waveguide (12). As a furtherfeature of the present invention, a controller (36) is disposed between the plurality ofelectrical leads (32) and the power source (38) for varying a magnitude and distribution ofcurrent among the individual portions (30) of the Bragg grating structure (14) to effectuatedifferent optical applications. |
