“…Because the frequency drift of these independent lasers can easily exceed the locking bandwidth for optical injection locking, precision temperature control or an additional optical phase-lock loop Manuscript must be used [1]. A device that provides increased temperature stability for sideband injection locking is multisection distributed feedback (DFB) lasers [3]- [6]. In this letter, generation and transmission of a data-modulated [binary phase-shift keying (BPSK)] optical MMW signal over up to 80 km of optical fiber using a two-section gain-coupled (TS-GC) DFB laser is demonstrated for the first time.…”

Transmission of 155-Mb/s binary phase-shift-keyingmodulated microwave/millimeter-wave (MMW) signal on an optical carrier over up to 80 km of standard single-mode fiber has been demonstrated experimentally using direct modulation of a two-section gain-coupled distributed feedback laser. Direct data modulation at an MMW carrier frequency of 25 GHz was enabled by on-chip optical injection locking. Index Terms-Analog transmission, microwave/millimeter-wave (MMW), optical injection locking, semiconductor lasers.

“…M ICROWAVE signal generation using an optoelectronic oscillator (OEO) [1] or by heterodyning two wavelengths from a dual-wavelength single-longitudinal-mode (DW-SLM) fiber ring laser (FRL) [2] has been considered two effective solutions for the generation of a high-frequency and ultra-low phase noise microwave signal, and can find important applications such as in radar, optical and wireless communications, microwave imaging, and modern instrumentation [3], [4]. For both an OEO and a FRL, to reduce the phase noise, a simple solution is to increase the loop length.…”

We report a novel method to generate a stable and frequency-hopping-free microwave signal based on a mutually injection-locked dual-wavelength single-longitudinal-mode fiber laser and an optoelectronic oscillator (OEO), with the mutual injection locking realized by sharing an optical path consisting of a polarization modulator and a polarization-maintaining phaseshifted fiber Bragg grating. The two wavelengths from the fiber laser are injected into the OEO to lock the generated microwave signal, while the microwave signal from the OEO is fed back into the fiber laser to injection lock the two wavelengths. Thanks to the mutual injection locking, the operation stability of the fiber laser and the OEO are substantially improved. A microwave signal at 11.8 GHz with a phase noise of −105 dBc/Hz at a 10-kHz offset frequency is generated. A stable operation of the system without frequency shifting and hopping is demonstrated.Index Terms-Erbium doped fiber amplifier, fiber Bragg gratings, fiber laser, injection locking, microwave, optoelectronic oscillator (OEO), phase shift, single longitudinal mode.

“…Electro-optical (E/O) modulators are also expensive in fabrication and do not easily lend themselves to integration. An all-optical way of producing mmw signals is to use the beat signal of several interfering lasing modes separated in wavelength by the RF frequency and originating from either a single laser or separate devices [3]. This approach is however hindered by the need for a coherent phase relation between the lasing modes.…”

In this article, analog fiber optic links (radio-over-fiber, RoF, links) are presented as a flexible, low-cost solution for in-house distribution of millimeter-wave (mmw) signals. Mode-locked laser diodes (MLLD) serve as inexpensive mmw sources for the downlink distribution of mmw signals across an optical fiber link. We compare the robustness of direct and external RF modulation for such MLLD-based RoF systems, whereas the error vector magnitude (EVM) of the received symbols serves as a figure of merit. On the eve of 60 GHz WLAN standardization, we experimentally investigate the transmission of narrowband WLAN (IEEE 802.11a) signals in the millimetric range at moderate data rates. We also demonstrate broadband transmission of multi-band orthogonal frequency-division multiplexing (MB-OFDM) ultra-wideband (UWB) european computer manufacturers association (ECMA 368) signals in the 60 GHz band for data rates of up to 480 Mbps.
