INSTRUMENTS SPECIAL POLARIZATION ACCESSORIES COMPONENTS APPLICATION FAQS GUIDE TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES - 26- General Photonics Corporation 909.590.5473 http://www.generalphotonics.com Notes: 1. Other options available. Contact General Photonics for details. 2. Stability specs listed apply to standard configuration with neutral DOP at an output larger than 80% of the maximum output power or driving current. Other options, such as low DOP, high DOP or high PER, may degrade stability. 3. High PER options for PER up to 45 dB are available. 4. Standard configuration is FC/APC. The SLD-101S is a highly stable superluminescent light source designed specifically for OCT, sensor and test & measurement applications. During operation, both the current and temperature are accurately controlled for superb power and spectral stabilities. The output power and diode temperature are stabilized to 0.02 dB and 0.05°C respectively. The light source has three operation modes: constant current, constant power, and modulated power. The modulation can be either external or internal, with different waveforms (sine or square) and different speeds (up to 100 kHz). One unique feature is that users can select either low or high degree of polarization (DOP) options for specific applications. Other user-selectable options include output fiber type (SM or PM), center wavelength (from 750 nm to 1600 nm), spectral width (20 to 80 nm), and output power. Finally, the SLD-101S comes with USB, RS- 232, Ethernet, and GPIB communication ports for easy, flexible interface with computers and other instruments. It is an ideal source for OCT, fiber sensors, fiber gyros, PM patch cord extinction ratio (ER) measurement, and general-purpose test and measurement.
