SLD-mCS/sCS-series Miniature High Power Broadband Light Source Modules Technical Product Specification
■SLD-mCS/sCS-series Miniature Broadband SLD Light Source Modules are wide-spectrum SM- or PM-fiber coupled light source modules for applications requiring a reliable, high-power, stable and low-noise SLD light source with a wide and flat spectrum and a short coherence length.
■SLD-mCS/sCS devices substitute SLD-MS light sources, providing better stability, higher efficiency, wider operating range and lower noise. They can be built using any SUPERLUM SLD if its drive current is less than 400 mA. They may be powered by a wide range of supply voltages, from 9 V to 30 V DC, and allow the use of switched-mode DC power supplies.
■Guaranteed operation temperature range is 0...+50℃ (case). Light source modules for a harsh environment applications, for example, for operation in extended temperature ranges (up to -40...+85 °С) are available upon request (depends on the P/N of the SLD used, i.e. the SLD drive current and voltage).
■SLD-mCS/sCS sources allow different control modes of SLDs. Modules with internal PD monitor may be driven in Constant Current (ACC) and Constant Power (APC) modes. SLD power can be set by internal potentiometer ("internal" control operation mode, INT) or controlled by 0-4 V analog voltage ("external" control operation mode, EXT). Operation modes can be selected using easily accessible jumpers.
■SLD-mCS/sCS sources ensure very high stability of SLD output over entire operating temperature range and low SLD noise. Particularly, the design of the controller used in both sources ensures that in the range from 10 kHz to 1 MHz there is no excess noise except for the SLD’s intrinsic quantum noise. In all standard models (i.e. those based on standard SLDs of Superlum) the SLD can be modulated (ON/OFF) at the rate of up to 50 kHz. SLD-mCS sources have FC/APC-terminated fiber pigtailed output. As a standard, the fiber is protected by a 3 mm tube.
■SLD-sCS sources have FC/APC mating sleeve. About 1 m long, terminated with FC/APC connectors on both ends, 900 μm buffered fiber cable is always enclosed to the SLD-sCS. The SLD-sCS has a little bigger chassis than the SLD-mCS. This allows the integration of additional elements like, for example, output power monitors, small size isolators and others.
■SLD-mCS/sCS sources have two control ports, “LOGIC” port for switching SLD ON/OFF and error indications, and“ANALOG” port for readout of SLD parameters and SLD power setting in “EXT” mode.
■When ordering the light sources with standard SLDs inside, just add “mCS” or “sCS” to SLD P/N not referring SLD module package type. For example, SLD-mCS-371-HP1-SM-PD describes SLD-mCS with a standard SMF fiber coupled SLD-371-HP1 module inside. Only butterfly packaged modules may be integrated into to SLD-mCS and SLD-sCS.
