摘要

Machining technology for LiNbO_3 (LN) wafer surface aiming a mass-production of broadband LN modulators is investigated. Although several manufacturers commercially supply 40G LN modulators, there are many difficulties in mass-production of such broadband LN modulators. For instance, in order to realize sufficiently broadened bandwidth performance, machining of LN wafer surfaces is necessary as demonstrated by ridge-waveguide modulators and devices using very-thin substrates. We focus the study on the machining technology of LN wafers applicable to mass-production based on micro-sandblast techniques. In order to demonstrate effectiveness of the micro-sandblast, 40G LN modulators designed to have a partially thinned substrate along RF-electrodes are experimentally fabricated.
