Hi guys, I am very new to this forum and its great to have a forum on laser.
Anyways, I am currently working on DFB lasers. My application field is Radio-over-fiber.
The question is, Im looking forward to purchase a DFB laser. But most of them are for digital application. Where it specificies the bandwidth in every DFB laser as 2.5 Gbps, or more.
So I understand that this is for digital. Only few I can find for analogue application where they specify the bandwidth as the frequency, like 1 GHz.
So what I dont understand is, can we modulate the digital DFB laser with an analogue signal? Cause I have an analogue signal centered at 2.7 GHz with 20 MHz bandwidth. I need to directly modulate them into a DFB laser. So please advice if I can use a DFB laser mend for digital application for this?
Thank you very much.
