Optical Mode Conversion Using Transistor Outline (TO) Techniques and a Ball Lens

Abstract

An apparatus comprises a transistor outline (TO) package comprising a TO can holder; and a TO can at least partially embedded within the TO can holder; and a mode converter coupled to the TO package. A system comprises a mode converter comprising a lens configured to convert a mode of a light from a first mode size to a second mode size, wherein the first mode size is smaller than the second mode size; a silicon photonic chip comprising a waveguide configured to communicate the light; a fiber configured to couple to the lens and the waveguide; and a substrate configured to provide a support for the silicon photonic chip.
