For the InP Membranes On Silicon (IMOS) platform [1], we developed an electro-optic modulator based on a slot-waveguide with a high nonlinear polymer. A variety of fabrication techniques are used, including electron beam lithography (EBL), optical lithography (OL), dry etching and metallization. The fabrication of such modulator requires a complex fabrication process. In this work we present and discuss the most important fabrication steps.
