NEAR INFRARED WDM
Fused Fiber WDM
The Near Infrared WDM enables the low loss combining or splitting of a pair of wavelengths within the 700 nm to 1199 nm region.
Gooch & Housego can rapidly produce such custom WDMs, with typical minimum wavelength separation of 50 nm.
Designed for applications in fiber laser, sensing, biomedical, military and avionics the WDM utilizes G&H’s low loss fused fiber technology. No light leaves the fiber and therefore no alignment is required. Furthermore the output fiber pigtails may be directly integrated into beam delivery systems.
Specific applications could include combining two sensor wavelengths onto one fiber, splitting laser harmonics, or combining wavelengths in fiber lasers.
For components which split optical signals of the same wavelength within the near infrared region please refer to the datasheet near infrared coupler.

1 For connectorized component, operating temperature range is –5 – +75oC.
2 For operation at powers of greater than 4 W the component housing and fiber must be adequately heat-sunk (for additional information contact G&H sales). Components intended for high power operation are only available in the 2x2 configuration. Component performance and reliability under high power must be determined within the customer system.
3 The performance and reliability of optical connectors is not guaranteed for optical powers of greater than 1 W.
