Top Illuminated Monitor Photodiode

Top illuminated InGaAs/InP monitor photodiode chip featuring a large optical aperture with a diameter of 150 µm and a dual pad layout. This product is optimized for monitoring the optical output power of Fabry-Perot (FP) and distributed feedback (DFB) lasers. The photodiode combines excellent responsivity in the wavelength region from 980 nm to 1620 nm, low dark current, and high ESD rating. The photodiode chip is manufactured with topside wire-bondable anode and cathode pads.


  • Easy coupling into large topside 150 µm optical aperture
  • Wide wavelength range from 980 nm to 1620 nm
  • High responsivity: 0.9 A/W
  • Low dark current: 8 nA
  • Cost effective, small chip size
