Low cross-talk, excellent frequency response characteristics and small terminal capacitance make Hamamatsu Corp.'s new indium gallium arsenide PIN photodiode array a match for DWDM monitors utilizing arrayed wavelength gratings.

The G8909-01 photodiode array covers the spectral response range of 0.95m to 1.75m, and can be designed into DWDM monitors that measure the integrity of optical channels in DWDM networks operating at 1.315m/1.555m, said the company.

Key specifications include a typical photosensitivity of 0.9A/W at 1.315m and 0.95A/W at 1.555m, and a typical crosstalk of -33dB.

Measuring 22-by-2-by-2.5mm deep and designed with precise chip-position tolerance, the G8909-01 features a pitch of 250mm, a 40-channel parallel readout and an active area of 0.08mm.

Pricing for the photodiode array starts at $453 in large OEM quantities. Delivery is eight weeks for sample quantities and 10 weeks for production quantities.
