DESCRIPTION

HAMAMATSU realized MSM (Metal-Semiconductor-Metal) Photodetectors having ultrafast responses.

The GaAs MSM Photodetector G4176-03 features 30 ps (design value) response time for both rise & fall while

keeping a low dark current (100 pA at Ta=25 C).

Symmetrical and interdigital Schottky contacts are fabricated at the sensitive area, whose size can be larger than

other kinds of fast response photodetectors. This makes easier to set up with optics. Therefore, MSM

Photodetectors are suited for measurements of optical high-speed waveform and optical communications.

There is no electrical polarity in MSM Photodetectors, that is, both polarities of a bias voltage are available, and

the polarity of an output signal depends on its connection.

Two kinds of packages are prepared for each MSM Photodetector. The package of G4176-03 is a coaxial metal

type (patent : Japan 2070802), which is easy to connect with an electrical SMA-connector. That of G4176-01 is a

TO-18, which is very common.

An optical fiber or connector input types are available as a custom option. Contact your local representative for

more information.
