“…Indirect phase noise reduction has been obtained in dual laser signal applications by noise correlation using frequency shifting [4], by optical injection locking [5], and by optical phase locking [6]. Here, we investigate the use of optical phase conjugate feedback (PCF) to obtain direct phase noise reduction in semiconductor lasers.…”

Abstruct-A theoretical analysis of the behavior of the frequency/phase noise of semiconductor lasers with external phase conjugate feedback is presented. It is shown that the frequency noise is drastically reduced even for lasers with butt-coupled phase conjugate mirrors. In this laser system, the phase noise takes a finite-low value corresponding to a state of first-order self-phase locking of the laser. As a result, the spectral shape of the laser signal does not remain Lorentzian but collapses around the carrier to a delta function with a close to carrier noise level of less than -137 dBcMz. The total phase variance of this laser signal, in a 20 GHz noise bandwidth, is less than 0.002 rad'.

“…Optical heterodyning also has the advantage over other generation techniques of generating high RF power, though optical sources with narrow linewidth or feedback loops are required during operation [13]. The following section includes descriptions of the most common techniques to generate microwave signals using the optical heterodyning method, including optical injection locking (OIL) of laser diodes [14], external modulation technique [15], dual-mode semiconductor laser sources [16] as well as using the optical phase locked loop (OPLL) configuration [17].…”

“…This situation is different for an optically generated microwave carrier because of the high amount of phase noise. The overall system performance can be achieved as required even if the transmitter phase noise (7) is slightly too high provided the phase noise at the demodulator input is as specified (8). Therefore, if the transmitter carrier must comply with the specifications for rms differential phase error given by (7) then the beat signal linewidth requirement is (9) but if the carrier specifications may be applied after the IF filter at the input of the demodulator then the beat signal linewidth requirement is found from (8)…”

Abstract-A coherent optical beam forming network principle using phase-locked semiconductor lasers as sources is presented. For this scheme the spectral purity of the intermediate frequency derived from mixing the signals from two semiconductor lasers is considered and the relationship between the linewidths of the lasers in a satellite transmitter and the phase error at the detector of a microwave differential quaternary phase-shift keying earth station receiver is analyzed. The demands placed on the linewidths from the point of view of phase stability requirements are calculated for coherent optical beam forming networks using quaternary phase-shift keying modulation at data rates of 33 and 131 Mb/s as examples. Furthermore, it is shown that a substantial improvement in performance can be achieved when phase locking the two lasers to each other is feasible.
