SD 048-11-21-000
Pump Laser
Monitor Photodiode
The SD 0480-11-21-000 Pump Laser Monitor Photodiode was designed to
monitor the optical power of short wavelength (500 to 1000 nm)
semiconductor lasers, such as the 980 nm EDFA pump laser. These OEM
detectors are supplied as bare die soldered to a ceramic block, which facilitates
integration of the photodiode together with the laser into standard
telecommunications packages.
The materials used in these products are selected to provide the extreme
longevity required by typical telecom applications. The ceramic mount is
metalized on both ends so that the detector can be readily soldered on its end to
the same substrate as the source laser. Ease of use is further enhanced by the
generous 0.7 mm x 1.0 mm active area of these detectors, which simplifies
optical alignment.
In addition to this standard configuration, API can also produce detectors in a
wide variety of custom configurations and packages. These detectors can even
be produced in monolithic arrays.
