“…Self-feedback and OIL were both studied to enhance the modulation bandwidth and reduce modulation chirp [67]. Up to 50 GHz bandwidth DML has been demonstrated using self-feedback [68], [69]. Compared to the self-feedback (essentially a laser which self-injectionlocks), OIL provides additional degree of freedom in the rate equations, which is frequency detuning ∆ω.…”

This paper reviews optical injection locking (OIL) of semiconductor lasers and its application in optical communications and signal processing. Despite complex OIL dynamics, we attempt to explain the operational principle and main features of the OIL in an intuitive way, aiming at a wide understanding of the OIL and its associated techniques in the optic and photonic communities. We review and compare different control techniques that enable robust OIL in practical systems. The applications are reviewed with a focus on new developments in the past decade, under the categories of 'High Speed Directly Modulated Lasers' and 'Optical Carrier Recovery'. Finally, we draw our vision for future research directions.

“…For what concerns the IF-DFB, the structure has been analyzed respect to the modulation characteristic in [10] and in many other papers on issues related to feedback stability, etc., mainly from the WIAS group. The extended modulation bandwidth characteristics and the use in telecommunication applications of IFB-DFB has been extensively demonstrated in various papers, [32][33][34][35][36] showing good experimental results.…”

In the last decades, various solutions have been proposed to increase the modulation bandwidth and consequently the transmission bit rate of integrated semiconductor lasers. In this manuscript we review some of them, trying to analyze for each one the mechanisms producing the modulation bandwidth extension. A comparison of the various approaches used for in-plane lasers is presented, in terms of both small and large signal modulation responses calculated using a Finite Difference Time Domain (FDTD) numerical simulator.

“…Similarly, the research work in [22] also presents a 40 Gb/s DML optical signal that used passive feedback laser (PFL) realized around 1300 nm and 1550 nm wavelength region. In this work, DFB and integrated passive feedback section (IPF) were combined enabling the suppression and control of the phase feedback field with the modulation performance of the stationary operating laser.…”

The demand for low-cost high-speed transmission is a major challenge for 5G future networks. To meet this optical communication demand, holistic and painstaking approaches are required in designing a simplified system model. Since the demands for high bandwidth are growing at unprecedented speed as we approach the Zettabyte era, it is crucial to minimize chromatic dispersion (CD) associated to high bit-rate signals. Mitigating CD electronically comes at high cost which may not be compatible with 5G. Photonic Integrated Circuit (PIC) as an enabler for fast speed optical transmission is still undergoing its growth stage and its major speed and efficiency have not yet been attained. However, proper and right combination of components and approaches can potentiate this technology in a more cost-efficient way. Hybrid modulation (HM)-PIC presents a simplified approach in terms of cost and efficiency for 5G networks. Hybridization of existing modulation components and approaches in PIC can enhance the generation of high bit-rate signals without the need for electrical CD compensation. A detailed study of hybrid multilevel signal modulation concept as a valuable solution for Data Centers (DC) high data-rate signals and next-generation Passive Optical Networks (PONs) is proposed.
