Transceiver VCSEL failure analysis
We've had a number of optical transceivers fail recently and I am trying to track down the cause. It has happened with two different models: HFBR-53A5VSEMZ (now obsolete), and the TSP-D1CH2-C11.
Some have failed after 18 months in the field, and…

Recommendations for modulation of VCSEL laserdiode configurations
For my project I need to design a cheap VCSEL laser driver which can be modulated up to 10 MHz. My laserdiode is VCSEL-1550 nm-T (built-in TEC and no monitordiode for APC). Datasheet link is here:…

Drive CW VCSEL Array
I want to build an array from VCSELS which I want to be able to turn on and off individually. My first thought was to just use a microcontroller, an external power source and MOSFETs to turn each VCSEL on and off individually. I'm not too keen on…
