The proliferation of 3D sensing applications such as facial recognition, gesturing, augmented reality in both consumer and industrial applications is driving the increased production of optoelectronics devices like laser diodes.

This is especially true for the Vertical Cavity Surface Emitting Laser (VCSEL), which is one of the primary components used in these 3D sensing systems. To minimize device self-heating, testing of the VCSELs are generally performed using “pulsed” DC. However, requirements to test at current levels up to 10A is driving the need to use pulses as short as 10µs in order to maintain reasonable self-heating levels.

We will be introducing the NEW Model 2601B-PULSE, which combines the full functionality of a Model 2601B SMU with a fast, high-current pulser capable of producing 10A pulses at up to 10V with pulse widths as short as 10µs.

In this webinar, we will be exploring:

• Key challenges for generating short current pulses and testing with them
• The impact of inductance in your test circuit.
• The importance of the cabling used in your test circuit.
• Some limitations of competing solutions, including the need to tune the source to the impedance of the device-under-test.
• The key features and benefits of the Keithley Model 2601B-PULSE.
