Product Overview

Tunable light source is a necessary instrument for wavelength related testing of passive and active devices in the field of optical communication. It can accurately and quickly adjust the appropriate wavelength to meet testing requirements. Coupled with a high sampling rate power meter, it can efficiently collect the power wavelength curve of the device and measure its performance parameters at different wavelengths.
TopLight Tunable Light Source is the first tunable light source developed by Dimension Technology, which integrates 16 years of professional experience in the field of optical testing. It has the characteristics of high wavelength accuracy, fast scanning speed, high output power stability, and no mode hopping in all bands. The product has high integration, compact size, flexible operation, and can be matched with the high-speed power meter and polarization controller of Dimension Technology to meet all testing requirements of wavelength division multiplexing devices.

Ultra high wavelength accuracy, repeatability, and stability, with stable output power

The TopLight tunable light source ensures a wavelength accuracy of ± 20pm through precise electromechanical control, ensuring reliable wavelength repeatability and stability even during high-speed scanning. TopLight can also compensate for environmental changes in different testing environments, ensuring stable and reliable wavelength accuracy.

The output power of the light source is strictly fitted for wavelength correlation, ensuring that the flatness of the power curve is higher than 0.2dB/nm, reducing the error caused by power on the testing system.

High output spectral signal-to-noise ratio and edge mode suppression ratio

TopLight uses the principle of external cavity resonance to tune the wavelength, and through precise optical and electromechanical control systems, ensures that the narrow linewidth laser output from the resonant cavity always has good signal-to-noise ratio and edge mode suppression ratio, providing an excellent testing environment and conditions for rigorous wavelength scanning systems.

Realize uniform and no mode hopping across the entire wavelength range, ensuring continuous wavelength curves

The integration ability of opto electromechanical computing in Dimension Technology provides a reliable guarantee for the mode control of tunable light sources. Through precise control and algorithms, TopLight can confirm that the laser always outputs the dominant mode wavelength while ensuring ultra-high scanning speed and wavelength accuracy. Testing can be completed without the need for wavelength calibration components during scanning.
