Scalable n x 14 Gb/s GaAs Photodiode

PD10Yx is a ultra small, short-wavelength GaAs photodiode array with optical apertures of 60 µm allowing easy coupling to multi-mode fibers. The scalable single photodiode chip is designed to form a multiple channel array with a pitch of 250 µm between the individual channels. The top illuminated p-i-n photodiode structure offers an excellent responsivity and high speed of response in the wavelength region from 830 to 860 nm.
The arrays are optimized for short reach 850nm VCSEL based high-speed parallel optical interconnects up to 14 Gb/s per channel. The photodiode pitch of 250 µm is suitable for coupling to fiber ribbon cables.


  • Large optical aperture: 60 µm
