High density integrated optical chip with low index difference waveguide functions

摘要

The invention features an optical chip having optical functions in large mode size waveguides. Under one aspect of the invention, the optical chip features one or more large mode field size waveguides, one or more low minimum bending radius waveguides to interconnect the large mode field size waveguides, and one or more optical functions integrated within or connected to the large mode field size waveguides.
