100 Gbit/s hybrid optical fiber-wireless link in the W-band (75–110 GHz) [PDF]
, 2011 We experimentally demonstrate an 100 Gbit/s hybrid optical fiber-wireless link by employing photonic heterodyning up-conversion of optical 12.5 Gbaud polarization multiplexed 16-QAM baseband signal with two free running lasers. Bit-error-rate performance

Remote downconversion with wavelength reuse for the radio/fiber uplink connection [PDF]
, 2006 The authors present a novel technology for uplink transmission in radio-over-fiber distribution systems. The technique employs remote downconversion of the uplink data to intermediate frequency (IF) in the base station (BS).

Multiple RF carrier distribution in a hybrid radio/fiber system employing a self-pulsating laser diode transmitter [PDF]
, 2002 A self-pulsating laser diode is used to generate a multicarrier microwave optical signal for use in a hybrid radio/fiber system. The self-pulsation frequency of the laser is controlled by external light injection, and can be varied between 14-24 GHz. The

A hybrid mode locked laser as millimetre wave modulated data source for radio-over-fiber systems [PDF]
, 2009 The paper presents a characterisation of a hybrid mode locked laser under external injection locking. It shows how such a system can be used to transmit baseband data without the requirement of an external ...
