Abstract
A receiver for demodulating optical OFDM signals may detect an optical OFDM signal that includes a carrier and data subcarriers by optically splitting the carrier from the subcarriers using a frequency selective filter and then recombining the carrier and the subcarriers using an optical coupler and balanced detector.
