SLD-based broadband light sources

Description

These series of SLD-based broadband light sources are designed for OEM applications. The light sources are ready-to-use compact devices that incorporates in a single unit an optical part and its driving electronics. The optical part of these light sources consists of a cooled SLD module (or, depending on a part number, of up to three broadband SLD modules with slightly shifted spectra, the emission of which is combined) and, optionally, an optical isolator. The driving electronics comprise a single or, depending on a part number, multiple high-precision, low-noise current and temperature controllers.

We offer a broad range of products, six device series, which can meet any specific requirements:

Interfaces for Remote Operation: analogue or digital (USB) interfaces are available.
Optical performance: single-, double-, or triple-channel optical output featuring ultra-broadband and high-power performance.
Optional isolation of the optical output.
Dimensions.

Product customization

We are capable to customize our products to meet any specific requirements:

1. Optical performance specifications. Other wavelengths are available (670 nm and the range from 900 to 1100 nm), output optical power can be fine tailored to a specific requirement, and so on.

2. Optical isolation. Optical isolation can be added to selected device series.

3. Device series. The product series designed for a certain number of channels are generally interchangeable.

4. Fiber connectors. The standard type of fiber connectors and sockets is FC/APC. Other types of fiber connectors are available on request, including SC/APC, LC/APC, E2000, as well as PC-type connectors (for optically isolated sources only).

5. Optical fiber. Single-channel sources can be assembled with any type of fiber listed below. Double- and triple-channel sources are assembled with SM fibers.
