Fabrication Of Vertical-Taper Structures For Silicon Photonic Devices By Using Local-Thickness-Thinning Process


Authors: Shunsuke Abe, Hideo Hara, Shin Masuda, and Hirohito Yamada. This paper describes a simple fabrication process of verticaltaper structures which can locally tune the thickness of silicon photonic devices. For low-loss spot-size conversion, taper angles less than 10° are required. To fabricate the gradual-slope shape of the vertical tapers, we have developed a step-andexposure lithog... » read more
