abstract = "We investigate the applicability of spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for optical transmitters in analog radio-over-fiber systems by using spin-flip rate equations. In addition to the current modulation for generating orthogonal frequency division multiplexing (OFDM) signals, we use the spin polarization modulation to excite a high-frequency polarization oscillation corresponding to a millimeter-wave carrier frequency. The polarization oscillation is converted to intensity modulation by using a polarizer, and the millimeter-wave carrier and the OFDM signals can be combined. Our results indicate that OFDM signals with millimeter-wave carrier can be generated by using the spin- VCSEL, and bandwidth of the current modulation in the spin-VCSEL limits data rate of the OFDM signals.",
