APD20C1
25 Gb/s APD with Integrated Lens
Ultra high speed avalanche photodiode (APD) chip with a T-shaped pad layout and an integrated backside lens. This innovative APD provides low noise multiplication and a high gain-bandwidth product which enables the design of high sensitivity 25G receivers. Typical applications include 100GBASE-ER4 and 28 Gbaud PAM-4.
The integrated backside lens focuses the incoming light beam on the topside detecting area, enabling an easy and efficient optical coupling.
