Description
The SMP devices are a range of single element Silicon
P.I.N. photodiodes. The device structure has be designed
to give maximum sensitivity and high speed of response.
The device structure shown above has a high resistance
intrinsic layer sandwiched between P and N+ layers.
Various optical filters can be incor porated inside the
package to pass selected regions of the ultra-violet to
infra-red spectrum. The optical filters can be ionically
coloured glass or vapour-deposited dielectric layers on a
glass substrate. For more details of the filter per mutations,
contact Semelab Plc.

The photodiodes are operated at zero bias for best sensitivity. Operation at reverse bias will enhance further the speed
of response. Typical circuits for these configurations are show below.
