“…It can be mentioned, however, that a great care must be taken when modulating a laser under relatively strong light injection. As shown in [18], only a part of the total locking range is dynamically stable. To operate the laser in this range and avoid an eventually severe instability, a suitable choice of the parameter values is necessary.…”

“…Under light injection, other interesting phenomena, such as locked or unstable regimes may be observed with different operating conditions. Locking occurs when the optical frequency of the injected light is chosen within the so-called locking range [17], [18]. This is the range over which the frequency of the slave laser can be tuned while still locked to the master laser frequency.…”

Abstract-A theoretical investigation of the second-and thirdorder intermodulation distortions (IMD's) in an injection-locked semiconductor laser under small-signal modulation is presented. The results show that a substantial reduction of the laser nonlinearity can be obtained, depending on both the injection level and frequency detuning between the master and slave lasers. The intensity modulation frequency response is also reported and shows that the injection-locked laser may also have a significantly improved behavior over the same free-running laser, revealed mostly in the reduced resonance peak and the broadening of the modulation bandwidth available.

Abstract-A bidirectional directly modulated cable passive optical network (PON) based on a reflective semiconductor optical amplifier (RSOA) as a colorless modulator in the optical network unit (ONU) is proposed and demonstrated.Good performances of downstream carrier-to-noise ratio (CNR)/composite second-order (CSO)/composite triple beat (CTB) and upstream bit error rate (BER) were achieved over a 40-km single-mode fiber (SMF) transmission. This proposed directly modulated cable PON is simpler and cost lower than the externally modulated one.

“…The form we used for our free running laser was very similar to those used before normalisation by Le Bihan and Yabre in [15]. In [16] Yabre neglects the gain compression factor, ε, by assuming that the optical power is moderate enough to allow the approximation (εS << 1) and hence (1-εS) ≈ 1.…”

The authors demonstrate how external light injection into a directly modulated laser diode may be used to enhance the performance of a multi-channel radio over fiber system operating at a frequency of 6 GHz. Performance improvements of up to 2dB were achieved by linearisation of the lasers modulation response. To verify the experimental work a simulation of the complete system was carried out using Matlab.Good correlation was observed between experimental and simulated results.
