In this image of the newly developed transmitter assembly, the small, brownish chip on the left is the electronic integrated circuit (EIC), and the larger, black-and-gold chip on the right is the photonic integrated circuit (PIC). The long structure on the left side of the PIC is the modulator, which converts the electrical signal into an optical one. Light gets coupled into and out of the chip through the fibers on the right side of the PIC. Everything is mounted on a printed circuit board (PCB), with gold wire bonds connecting the chips. Data flows from left to right, where the incoming electrical signal gets amplified by the EIC, converted to an optical signal by the PIC, and sent out via fiber to its destination.

The gravitational waves emitted by the merger of black holes, when lensed by massive objects as the waves travel toward Earth can be used to calculate the rate at which the universe is expanding
