         List of Products             WDM
 
            Near Infrared WDM
 

The Near Infrared WDM enables the low loss combining or splitting of a pair of wavelengths within the 700nm to 1150nm region. G&H can rapidly produce such custom WDMs, with typical minimum wavelength separation of 50nm.

 

Designed for applications in fibre laser, sensing, biomedical, military and avionics the WDM utilises G&H’s low loss fused fibre technology. No light leaves the fibre and therefore no alignment is required. Furthermore the output fibre pigtails may be directly integrated into beam delivery systems.

 

Specific applications could include combining two sensor wavelengths onto one fibre, splitting laser harmonics, or combining wavelengths in fibre lasers.

 

For components which split optical signals of the same wavelength within the near infrared region please refer to the datasheet ‘Near Infrared Coupler’.

          PM WDM
 

The G&H Fused PM WDM, combines multiple wavelengths of light in PM Fibre whilst maintaining polarisation. G&H proprietary PM manufacturing technology provides low loss, with high polarisation extinction ratio. The all fibre construction offers excellent reliability and high power handling characteristics.

 

These high performance parts are available in many wavelength configurations, housing, fibre and connector options and can therefore be readily specified in a wide variety of applications, enabling rapid design cycles and new project builds.

 

In common with all PM components, it is necessary to launch into either the slow or the fast axis to maintain polarisation. For the G&H PM WDM, specifications are based on slow axis launch, although fast axis versions are also available if requested

 

Key Features:

Low Loss
