Hamamatsu launches InGaAs PIN photodiodes

InGaAs PIN photodiodes
Hamamatsu Photonics has introduced the G10899 Series of InGaAs PIN photodiodes, featuring a very wide spectral response range of 0.5 to 1.7um.
Standard InGaAs PIN photodiodes only offer a useful response range from 0.9 to 1.7um, with silicon photodiodes being used to cover from 400nm to 1.1um.
The G10899 can provide the end user with the ability to implement only one detector, where in the past they might have needed two.
This feature lends itself well to the optical communications field, since the G10899 has high sensitivity at three of the commonly used wavelengths for optical communications (850nm, 1,310nm and 1,550nm), whereas a standard InGaAs detector would have very low response at 850nm.
The G10899 Series is available in three standard active-area sizes, 1, 2 and 3mm, with the 1mm device operating at bandwidths up to 45MHz and with a very low dark current, typically 1nA.
In the optical communications sector, the G10899 Series is most useful for use in optical power meters, OTDRs, tunable laser diode monitors and free space communications, as well as other network monitoring applications.
The properties of this range of devices also make them suitable for spectral analysis, industrial inspection and temperature sensing applications.
