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: ...

Laser driver current and temperature management
For a project I need to make a custom laser driver for a dot green laser module.
Below and here 1 you can find my design, the laser I've using now is a PLT5 510 OSRAM, the VSYS is 3,7 V DC from a Li-...

Driving a 14-pin with DFB laser using D2570H
For our project, we would like to use the D2570 DFB laser from Agere system since it has a built-in photodiode with a TEC sensor, thermistor and a bias-tee embedded in an 'all-in-one' package.
However,...

Is there a difference between rise and fall time and modulation frequency
I was wondering if there was a difference between modulation frequency and rise and fall times of a laser diode or LED? If a laser had a modulation frequency of 100MHz would that be the same as a rise ...

What is current modulated laser driver? What does it do to the laser?
The title is actually one of the many questions I have. I've started to work on a project that includes lasers. I've worked with lasers and fiber optics before and I even constructed a simple constant ...

Help designing a circuit to drive a 1550nm DFB LD and use it to modulate an RF signal
I need to modulate an RF signal (random sine wave acting as data) using the 1550nm DFB Laser Diode, I need a control circuit to drive the Laser Diode and inject the data to modulate the LD carrier ...
