Abstract:
PROBLEM TO BE SOLVED: To provide an integrated optical modulator which can minimize an influence of chromatic dispersion and has a more simplified configuration by connecting a carrier wave band modulator using a double sideband modulation method and an intermediate frequency band modulator using a single sideband modulation method in series, and to provide a method for manufacturing the integrated optical modulator. SOLUTION: The integrated optical modulator comprises the carrier wave band modulator using the double sideband modulation method and the intermediate frequency band modulator using the single sideband modulation method. The carrier wave band modulator and the intermediate frequency band modulator are connected in series. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
PURPOSE: An electrostatic wavelength varying filter is provided to uniformly and widely control the thickness of the electrostatic wavelength varying filter by forming a spacer layer with UV imprinting or thermal imprinting mold process. CONSTITUTION: A membrane layer(120) is formed on a first substrate(110). A first high reflection filter layer(130) and a first electrode(140) are formed on the membrane layer. A part except for the first high reflection filter layer and the first electrode is eliminated. A spacer layer(170) is formed on a second substrate(150) with an imprinting mold process. A part of the spacer layer is depressed in order to be corresponded to the first high reflection filter layer. A second electrode is formed on a projected portion of the spacer layer. A device is formed by bonding the first substrate and the second substrate.
