The dots, composed of a semiconductor called indiumphosphide, are sprayed onto a transparent plastic sheet that is then covered with a second sheet. That done, the whole thing is heat-sealed.
The Quad PD Arrays consist of four photodiodes monolithically integrated on a common indiumphosphide (InP) substrate, and are fabricated using a low FIT rate InGaAs/InP semiconductor process.
