Ultra high speed avalanche photodiode (APD) chip with a Y-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 28 Gbaud PAM-4, 100GBASE-ER4 and 25G EPON.
The integrated backside lens focuses the incoming light beam on the topside detecting area, enabling an easy and efficient optical coupling.
