We report on advanced millimeter-wave (mm-wave) photonic components for broadband wireless transmission. We have developed self-pulsating 60 GHz range quantumdash Fabry-Perot mode-locked laser diodes (MLLD) for passive, i.e. unlocked, photonic mm-wave generation with comparably low phase noise level of-76 dBc/Hz @ 100 kHz offset from 58.8 GHz carrier. We further report on high-frequency 1.55 µm waveguide photodiodes (PD) with partially p-doped absorber for broadband operation (f 3dB~7 0-110 GHz) and peak output power levels up to +4.5 dBm @ 110 GHz as well as wideband antenna integrated photomixers for operation within 30-300 GHz and peak output power levels of-11 dBm @ 100 GHz and 6 mA photocurrent. We further present compact 60 GHz wireless transmitter and receiver modules for wireless transmission of uncompressed 1080p (2.97 Gb/s) HDTV signals utilizing the developed MLLD and mm-wave PD. Error-free (BER=10-9 , 2 31-1 PRBS, NRZ) outdoor transmission of 3 Gb/s over 25 m is demonstrated as well as wireless transmission of uncompressed HDTV signals in the 60 GHz band. Finally, an advanced 60 GHz photonic wireless system offering record data throughputs and spectral efficiencies is presented. For the first time, we demonstrate photonic wireless transmission of data throughputs up to 27.04 Gbit/s (EVM 17.6 %) using a 16-QAM OFDM modulation format resulting in a spectral efficiency as high as 3.86 bit/s/Hz. Wireless experiments were carried out within the regulated 57-64 GHz band in a lab environment with a maximum transmit power of-1 dBm and 23 dBi gain antennas for a wireless span of 2.5 m. This span can be extended to some 100 m span when using highgain antennas and higher transmit power levels.

Recent activity to achieve multi-gigabit transmission over 1 mm core diameter graded-index and step-index plastic optical fibers for distances up to 50 meters is reported in this paper. By employing a simple intensity-modulated direct-detection system with pulse amplitude or digital multi-tone modulation techniques, low-cost transceivers and easy to install large-core POFs, it is demonstrated that multi-gigabit transmission up to 10 Gbit/s over 1-mm core diameter POF infrastructure is feasible. The results presented in this paper were obtained in the EU FP7 POF-PLUS project, which focused on applications in different scenarios, such as in next-generation in-building residential networks and in datacom applications.
