Why are you focusing on VCSEL anyways? Standard laser diodes already have a modulation bandwidth that goes into several 100MHz, the better ones should give you 1-2GHz. With that, you should be within 6dB, maybe 10dB of the CW power. Given that you only need a few 10µW to 100µW of laser power, and that those diodes are in the 1-30mW range should give you enough margin.
