A novel phase-modulation to
intensity-modulation (PM-to-IM) converter is proposed and experimentally
demonstrated basing on a vertical-cavity surface-emitting laser (VCSEL).
Comparing with the published schemes, in which the employed DI, FBG, OBPF or dispersion
devices can only process a certain phase-modulated RF signal, the proposed
scheme can achieve the conversion process in an economic and resourceful
manner. To be the first one of achieving such PM-to-IM conversion process by a
VCSEL, the feasibility of the proposal is experimentally demonstrated with an
open eye diagram when it is employed to convert phase-modulated RF signal.
