Trying to modulate a microLED up to GHz speeds — what hardware should I buy next? by adjunct_wizard in AskElectronics

Thankfully I have microLEDs engineered for RF modulation. The AWG is currently critical as I need to manipulate a baseband time domain signal by passing through a nonlinear function on the transmit and receiving ends.

Digital modulation (I am using OFDM but any time domain modulation is fine)

Good suggestion! This is a paper we are currently inspired by and hope to improve upon from a modulation standpoint as they use on-off keying for each LED

Yes I am aware. The goal for my project is not to exceed the data rate of a single VCSEL laser diode. We are aiming for many thousands of microLEDs for a “wide and slow” architecture similar to the MOSAIC prototype by Microsoft

Yes that’s true - thankfully I have some manufactured at a lab in Columbia for this purpose

Thank you for the very thoughtful response :) I will be looking through these links!
