Source Measurement Solution Case Study for VCSEL / LD Testing Application

Source Measurement Solution Case Study for VCSEL / LD Testing Application

Overcoming Source Measurement Obstacles

Case Study

The Challenge:

Headquartered in Taiwan, MPI Corporation produces a wide range of technology products ranging from probe cards and production LED/Photonics test equipment to advanced semiconductor test equipment and eco-minded thermal products. Developing these innovative technologies requires reliable, cutting-edge test equipment to validate, troubleshoot and optimize designs for their customer’s demanding applications.

With VCSEL applications being a key focus market, MPI needed a Source Measurement Unit (SMU) that was well-suited for a variety of testing applications (see below) Tektronix’s innovative and efficient SMU product has enabled MPI to provide ideal solutions for their customers.

Vertical Cavity Surface Emitting Laser (VCSEL) Testing

Known to be temperature-sensitive, VCSEL emission spectra are altered by the temperature dependence of the refractive index and the thermal expansion of the resonator material. This leads to varying power curves and optical uniformity. VCSEL testing requires precise current control to avoid damage to both the DUT and probe.

Light Intensity-Current-Voltage (LIV) Testing

Typical SMU’s designs can only deliver longer pulses (>100ms) and require multiple instruments to measure LIV electrical test parameters (If, Vf, Vr, ILeakage, VBreakdown).

Laser Diode (LD) Testing

When outputting current pulses, cabling and inductance can be problematic for laser diode testing. Because inductance resists current variations, the current source may overcompensate the output voltage resulting in overshoot and ringing as the pulse settles.

The Solution:

Tektronix’s 2601B-Pulse SMU has helped MPI streamline its product development by addressing these challenges with a handful of key features.

  • Combining the capabilities of multiple instruments like voltage sources, DMMs, and

switches

into one reliable device means less time building and tuning complex setups and more time

making real progress on product development.

  • The 2601B-Pulse control loop system constantly adjusts the output for load changes

minimizing overshoot or ringing when outputting a pulse from 10 μs to 500 μs up to 10 amps.

  • PulseMeter™ Technology minimizes the risk of damaging VCSELs and burning out probing

equipment.

  • Dual 1 MS/s digitizers enable capturing the source output and measurement simultaneously

making it easier to review test results quickly without the need for a separate instrument.

  • TSP-Link technology together with TSP technology enables high-speed, SMU-per-pin

parallel testing and low-latency communication. This makes testing multi-zone VCSELs in

parallel and improving throughput much more accessible.

Thoughts from the Customer

  • “The 2601B-PULSE one-box unit gives exactly what our customers need for measuring high

current output, low current sensitivity and short pulse solutions with significantly less

damage to both DUTs and probe tips.” Hector Lin, Product Development Manager.
