Abstract

An optical input/output chiplet is disposed on a first package substrate. The optical input/output chiplet includes one or more supply optical ports for receiving continuous wave light. The optical input/output chiplet includes one or more transmit optical ports through which modulated light is transmitted. The optical input/output chiplet includes one or more receive optical ports through which modulated light is received by the optical input/output chiplet. An optical power supply module is disposed on a second package substrate. The second package substrate is separate from the first package substrate. The optical power supply module includes one or more output optical ports through which continuous wave laser light is transmitted. A set of optical fibers optically connect the one or more output optical ports of the optical power supply module to the one or more supply optical ports of the optical input/output chiplet.
