“…The green curve in Fig.4 shows the spectra of the received back-to-back (BtB) DMT signal without any OIL: the 3 dB modulation bandwidth was only 4.4 GHz with a fast roll-off at higher frequencies. With the OIL, we observed a remarkable enhancement of the modulation bandwidth due to the photonto-photon interaction due to OIL [24]. At a ∆ of 31 GHz, the signal spectrum has a smooth roll-off, which is similar to the roll-off of the AWG's electrical output.…”

“…We set the injected power to 4 dBm, as above this power we started to observe some instability in the OIL process. For lower powers, we achieved smaller transmission capacity, which was a consequence of a smaller locking range [24]. The optical spectra generated using the higher-bandwidth AWG and corresponding electrical spectra after direct detection when ∆ was varied from 17 to 31 GHz (the region that gave the best performance in terms of the transmission capacity discussed later) are shown in Fig.…”

“…The modulation characteristics/bandwidth of a laser under OIL depends on the frequency difference ∆ between the carrier frequency of the master laser ( ) and the carrier frequency of the free running slave laser mode ( ) [24], [25]. It also depends on the power injected from the master.…”

Abstract-The 2-µm wave band is emerging as a potential new window for optical telecommunications with several distinct advantages over the traditional 1.55µm region. First of all, the Hollow-Core Photonic Band Gap Fiber (HC-PBGF) is an emerging transmission fiber candidate with ultra-low nonlinearity and lowest latency (0.3% slower than light propagating in vacuum) that has its minimum loss within the 2-µm wavelength band. Secondly, the Thulium-doped fiber amplifier that operates in this spectral region provides significantly more bandwidth than the Erbium-doped fiber amplifier. In this paper we demonstrate a single-channel 2-µm transmitter capable of delivering >52 Gbit/s data signals, which is twice the capacity previously-demonstrated. To achieve this we employ discrete multi-tone (DMT) modulation via direct current modulation of a Fabry-Perot semiconductor laser. The 4.4-GHz modulation bandwidth of the laser is enhanced by optical injection locking, providing up to 11 GHz modulation bandwidth. Transmission over 500-m and 3.8-km samples of HC-PBGF is demonstrated.

“…Different kinds of optical perturbations exist, such as optical injection [1] or optical feedback from a conventional mirror [2] or from a phase-conjugate mirror [3]. They have all been intensively studied both theoretically and experimentally in order to understand why the performance of a diode laser (DL) is sometimes improved and sometimes degraded by these perturbations.…”

Abstract-We report on the systematical investigation of the steady-state regime and the dynamical behavior of a semiconductor laser subject to delayed filtered optical feedback. We study a Fabry-Perot (FP) interferometer type of filter placed in the external feedback loop of a diode laser. The effects of the filter on the locking of the diode laser frequency to the external cavity modes are described. We report and observe hysteresis, bistability, and multistability and show that all these are well described by a set of rate equations for the coupled laser and FP cavity system. We also present an experimental stability diagram that summarizes the dynamical behavior of the system.
