Swept wavelength tunable laser source combines speed, low noise, versatility

August 10, 2005 Boulder, CO -- dBm Optics has introduced its Model 4200 Tunable Laser Source. The company says the device offers 2,000-nm/sec tuning over 150-nm wavelengths. A low-noise version of the device is available for measurements requiring high dynamic range, such as the characterization of fiber-Bragg gratings. A high-power version, with greater than 8 dBm (6 mw) of output power over the entire tuning range, is also available for applications requiring more power.

A variety of options, which can be built directly into the instrument, are available to turn the device into a fully-controlled and characterized optical source, according to the company. Options include wavelength reference, VOA, and polarization controller/scrambler. The device incorporates a color touch screen, while also supporting all-button operation. A PC can be used to set and monitor the device's parameters through Ethernet, USB, and GPIB (IEEE 488) interfaces.
