Title:
BROAD BAND LIGHT SIDE BAND GENERATING METHOD, AND BROAD BAND LIGHT SIDE BAND GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/052683
Kind Code:
A1
Abstract:
A light beam is input to an electrooptic phase modulator from a laser light source to subject the light beam to phase modulation, and a specified phase modulation index spatial distribution is set so as to offset the spatial distribution of the light beam, thereby generating a light side-band row having a uniform intensity distribution.
