Multi-Functional Integrated Optics Chip (MIOC) includes a linear polarizer, acts as polarizer and depolarizer; a Y-branch waveguide, acts as optical power splitter and combiner; and two pairs of push-pull electrode function as electro-optic phase modulator.
The design and process of MIOC is optimized , with high reliability, low insertion loss, high polarization extinction ratio. Micro-electronic and micro-optical processes, and fiber pigtail precision alignment are taken in the MIOC.
