Superlum T- and Q-series Broadlighters are broadband, very low coherence AC powered benchtop light sources based on three (T-series) and four (Q-series) fiber coupled superluminescent diode modules with slightly shifted central wavelengths, the emissions of which are combined by appropriate broadband singlemode fiber couplers to achieve the best combination of output power and spectrum width. The design of SLD module controllers ensures excellent operation stability of the light sources.

The devices are developed for optical test and measurement applications including:

• Optical coherence tomography
• Characterization of optical components
• Optical fiber metrology
• Optical measurements

From July 2005, all T- and Q-series Broadlighters are delivered with RS-232 remote control capability. Superlum offers companion software to operate your T- or Q-Series Broadlighter remotely from your PC/laptop. Please see the downloads page for details.

The following T- and Q-series Broadlighters are commercially available:

• T840: A 100-nm light source at 840 nm with an output power of 15 mW.

• T870: A 180-nm light source at 870 nm with an output power of 8 mW.

• Q870: Combines the spectra of four SLD modules. A 200-nm FWHM bandwidth with an output power of 5 mW.

• Q940: A mean wavelength of 940 nm. A 300-nm FWHM bandwidth with an output power of 4 mW.

• Q1350: A mean wavelength of 1370 nm. A 200-nm FWHM bandwidth with an output power of 5 mW.

• Q1430: A mean wavelength of 1430 nm. An FWHM bandwidth of up to 250 nm. An output power of 5 mW.
