| 英文摘要 | PURPOSE:To enable the modulation up to approx. 30GHz with a modulator using a laser diode by enclosing a part led to the exterior of a waveguide of a metallic rod extending to contact with the laser diode disposed at specific position at the center of the waveguide with a radial filter. CONSTITUTION:A laser diode 33 is disposed at the position isolated at 1/4 wavelength of modulated wave from a terminating shortcircuit plate 31 at the center of a waveguide 24. The other end of the metallic rod 21 extending to contact with the diode is let to the exterior of the waveguide, and the periphery is enclosed with a radial filter 22. A light machting unit 32 is disposed to confront the duide 33. Thus, a modulator capable of effectively modulating the light output within the frequency range of several GHz to 30GHz can be obtained. |
