Precise and Robust Fibre-Coupled APDs and Pulsed Laser Diodes

Photonics News No 50

UK50-0350

Fibre-coupled avalanche photodiodes (APDs) and pulsed laser diodes (PLDs) are engineered and produced by LASER COMPONENTS. The robust, hermetic assembly is ideal for many applications. For example, high-power PLDs (as the laser source) and suitable low-noise InGaAs APDs are used for distributed temperature sensing (DTS) applications, and Si Geiger-mode APDs are used for photon counting.

The fibres are aligned and fixed with high positional accuracy and close to the detector active area, or laser source, making the fibre-coupled devices especially ideal for sensing applications.

Flexible assembly technology allows almost every combination of optical fibre and APD – Si or InGaAs. In principle, all PLDs can also be supplied with a fibre connection – no matter which wavelength is required: 850 nm, 905 nm and 1550 nm.

All fibres with Ø400 µm core can be coupled. The devices can also be terminated with FC/PC or SMA connectors upon request. To optimise coupling efficiency, the fibre end faces can be finished with an AR coating. These robust components can be used across a wide temperature range; their design goes far beyond the requirements of the Telecordia GR468 directive.

Have a look at our accessories as well: whether you need suitable driver electronics for a PLD or a high voltage supply for APDs, you obtain everything from one source.
