Chroma ATE, a world leading supplier of electronic test, measurement, and manufacturing equipment,
has unveiled its new Chroma 58173-V Laser Diode Test System at SPIE Photonics West in San Francisco, CA this week.
The Chroma 58173-V Laser Diode test system provides a total solution for VCSEL production lines from wafer to final
package and is accurate enough to be used in research & development and QA environments for device characterization and validation.
Key features of the system include fine resolution CCD scanner with precision wafer mapping, high-speed automated prober,
a temperature controlled chuck, and a wide spectral range for both power and wavelength measurement.
The Chroma 58173-V Laser Diode test system is compatible with wafer, die, chips and numerous package types including TO-Can and LCC.
The system’s highly compact design is a result of Chroma’s history of research and engineering experience with semiconductor and LED
solutions. It offers precision testing on a stable platform with intuitive functionality & operation. Solution flexibility allows
for adaptation to differing laser diode applications.
Chroma 58173-V system is suitable for wide range of wavelengths from visible to long wavelength (500~1600 nm) by selecting the
respective optical module & software settings. Using an integrated sphere along with solid test methodology, the system gathers
the necessary data from the VCSEL under test including LIV sweeps, threshold current, spectrum characteristics & defect curve.
A thermal chuck & packaged device holder allow for wafer, die, or chip testing in various temperature conditions and yields
correlation between wafer & final package performance. The Chroma 58173-V provides an ultra-clean current source by taking advantage
of Chroma's 52400 series 4-quardrant PXI Source Measurement Unit (SMU). This SMU offers 7 current force/measured ranges (200 mA max)
with low noise & high accuracy to protect the VCSEL or other surface emitting laser diode. High slew-rate driver provides μs pulse
to CW for various test applications.
