Electronic Integrated Circuits, or chips, revolutionized modern technology enabling the creation of smartphones, laptops, and even self-driving cars. However, they come with drawbacks. Current chips lose 20-30% of their energy due to heat (Thompson 2006). This limits the amount of data that can be transmitted at any given time. On the other hand, Photonic Integrated Circuits (PICs) improve on these issues. The use of photons minimizes energy losses and increases the bandwidth of data transmission. In this paper we will talk about the characterization of photodetectors on a PIC. We aimed to find the frequency at which the optical to electrical conversion of a PIC photodetector becomes unusable, the electrical bandwidth. By utilizing a Lightwave Component Analyzer, we were able to amplitude modulate the laser from 10 MHz to 67 GHz. We found that for both 1550 nm and 1310 nm the photodetector data became indistinguishable from dark current output at 26.5 GHz
