Co-packaged optics system with a laser source and a bi-directional laser medium

An optical system, comprising:

• a laser source to provide an optical signal having a first polarization;
• a first polarization element to:
• receive the optical signal from the laser source and provide the optical signal to a second polarization element via a polarization maintaining medium,
• receive a second modulated optical signal from the second polarization element via the polarization maintaining medium, the second modulated optical signal having a second polarization,
• manipulate a polarization of the second modulated optical signal to create an output signal having the first polarization,
• provide the output signal to an output of the optical system;
• and
• the second polarization element to:
• receive the optical signal from the first polarization element via the polarization maintaining medium and provide the optical signal to a transmitter,
• receive a first modulated optical signal from the transmitter, the first modulated optical signal having the first polarization;
• manipulate a polarization of the first modulated optical signal to create the second modulated optical signal, and
• provide the second modulated optical signal to the first polarization element via the polarization maintaining medium.

A laser module, comprising:

• a laser source;
• a polarization element including:
• a first port to receive an optical signal provided by the laser source, the optical signal having a first polarization;
• a second port to provide an output signal having the first polarization;
• a third port to:
• provide the optical signal received at the first port, wherein the optical signal is to be provided to a polarization maintaining medium, and
• receive a modulated optical signal having a second polarization, wherein the optical signal is to be received via the polarization maintaining medium;
• and
• a set of optical elements to manipulate a polarization of the modulated optical signal received at the third port to create the output signal provided at the second port.
