PD10Kx
Scalable 4 x 10 Gb/s GaAs PD Array
Scalable 4 x 10 Gb/s short-wavelength GaAs photodiode array with large optical apertures allowing easy coupling to multi-mode fibers. The scalable 1 x 4 array is designed such that the photodiode pitch of 250 µm is maintained across the border of the 1 x 4 basic cell. The photodiode pitch of 250 µm is suitable for coupling to fiber ribbon cables. The basic cell can be repeated n times to provide scalable arrays of 4, 8, 12 or more individual photodiode channels.
The arrays are optimized for short reach 850 nm VCSEL based parallel optical interconnects with a speed of up to 10 Gb/s per channel. 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.
