Abstract
In order to obtain an optical module which has few components and is simple to assemble and miniaturize, and a method of configuring same, an integrated prism is provided with: a polarization rotating unit which is formed on the external surface of the prism and converts the polarization of first input light into third light having a polarization perpendicular to the polarization of second input light; and a polarization multiplexing unit which is formed on the inner surface of the prism and multiplexes the polarizations of the second and third light to output fourth light including the second and third light.

An integrated prism comprising:
- a polarization rotator that is formed on an external surface of a prism and configured to convert a polarization of input first light into third light having a polarization perpendicular to a polarization of input second light;
- and
- a polarization multiplexer that is formed on an internal surface of the prism, configured to multiplex polarizations of the second light and the third light, and configured to output the polarization as fourth light including the second light and the third light.
