In this paper we present the remarkable characteristics of quantum dash mode-locked lasers and how they could be used for low phase noise signal generation, for high data rate wireless transmission and radar in the millimeter wave frequency range.

This paper summarizes the motivations and results obtained regarding the optical distribution of a 60 GHz radio signal throughout buildings to provide users with Ultra-Broad-Band Wireless Home Area Network with datarates >1Gbps and continuous coverage.

In this paper, we present a simple architecture for a super-broadband 60 GHz photonic wireless system. Using a cascaded optical RF and data modulation approach, advanced photonic components and a high-spectral efficient QAM-OFDM modulation format, we realized a compact 60 GHz photonic wireless system having a spectral efficiency as large as 3.86 bit/s/Hz. By making use of the 7 GHz spectral bandwidth in the 60 GHz band which was opened up for unlicensed broadband wireless services worldwide, we achieved record data throughputs. For example, by using a 16-QAM OFDM subcarrier modulation, we experimentally demonstrate photonic wireless transmission of 27.04 Gbit/s with a mean EVM of 17.63%. Wireless experiments were carried out 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 can be extended to some 100 m span when using high-gain antennas and higher transmit power levels.

Some of the work carried out within the European integrated project Integrated Photonic mm-Wave Functions for Broadband Connectivity (IPHOBAC) on the development of photonic components and radio-over-fiber technologies for broadband wireless communication is reviewed. In detail, 60 GHz outdoor radio systems for >10 Gbits/s and 60 GHz indoor wireless systems offering >1 Gbit/s wireless transmission speeds are reported. The wireless transmission of uncompressed high-definition TV signals using the 60 GHz band is also demonstrated.

We propose and validate a new radio-over-fibre (RoF) home network architecture allowing a 60 GHz wireless signal bidirectional distribution, based on a set-up of new 60 GHz components (Mode Locked Laser and Reflective Electro-Absorption Modulator).

In this paper, we demonstrate and compare experimentally two techniques achieving very high-data-rates (> 1 Gb/s) wireless transmission in the 60 GHz window using radio over fiber (RoF) for reach extension. The first RoF link is based on a 10 GHz vertical-cavity surface-emitting laser and uses a multimode fiber. The radio signal is transported on an intermediate frequency of 4.5 GHz and electrically upconverted to 60 GHz after the optical link. The second uses an optical frequency upconversion from 4.5 to 60 GHz by direct modulation of a mode-locked Fabry-PEacuterot laser whose self-pulsating frequency is 54.8 GHz before transmission over a single-mode fiber. For both techniques, two different types of modulation were tested. The first one was an on-off keying at 1.5 Gb/s and the second one was an orthogonal frequency-division multiplexing-QPSK signal compliant to the IEEE 802.15.3.c prestandard (3.03 Gb/s). Radio propagation performance is also reported.

We demonstrate and compare experimentally two set-ups achieving very high data rate (3 Gbps) wireless transmission in the 60 GHz window, both using Radio-over-Fiber (RoF) for reach extension with OFDM signal compliant to the IEEE 802.15.3.c pre-standard.
