T500S - High-power continuously tunable laser

Faster and highly reliable testing for optical components, including photonic integrated circuits.

Optical spectral characterization—rapid, reliable and repeatable

A continuously tunable laser is an essential instrument in R&D labs and on production floors. It covers a variety of applications where rapid, continuous wavelength tuning is required. The T500S offers excellent wavelength coverage, delivers speed and high power while sweeping. The laser also shows excellent linewidth characteristics when operated at fixed wavelength.

Integrated photonics can include complex optical components with high-contrast spectrum. For instance, a ring resonator may have very sharp features making it difficult to characterize insertion loss. Furthermore, some devices also require extended measurements of return loss or polarization dependent loss, with the same level of precision. Finally, simultaneous testing of many devices or outputs from one single device is also required to speed up PIC characterization. To test such devices, the T500S laser can be jointly operated with the CTP10, EXFO’s component testing platform. With high-resolution and high-accuracy spectral measurement, the CTP10 is an integrated solution that leverages the full potential of the T500S for operations at 200 nm/s sweep speed with bidirectional scanning. The T500S is also compatible with the CT440, EXFO’s compact component tester operating at 100 nm/s.
