Hello, I'm trying to make my first laser circuit.
I'm trying to beam information with a data stream, i.e off/on
I found this circuit in a book, but i don't understand how to determine the proper resistances and bias voltage.

I'm using a hitachi HL6335G 635nm, 5mw diode
Any circuit theory help would be greatly appreciated!

I'm also highly interested in the proper term for this type of circuit so i can google more efficiently.
Is it modulated? laser driver? i'm not really sure what to call it
