Vias are formed by 5 min wet etching in BOE.
linb3o The measured tuning efficiency is 7. Express 26 23 The light blue region indicates the waveguiding core in each circumstance. Shallow rib waveguides are utilized for guiding a single transverse electric TE optical modularor, and Au coplanar waveguides CPWs support the modulating radio frequency RF mode. Alert me when this article is cited. The fabricated modulator possesses a tightly confined optical mode, which lends itself to a strong interaction between the modulating RF field and the guided optical carrier; resulting in a measured DC half-wave voltage of 3.
