“…Researchers have also innovated new transmitter architecture using OIL DML to reduce the carrier to signal power ratio to facilitate more power efficient transmission with improved performance [73]. Different types of lasers, such as VCSEL [74], [75] and microring lasers, have also been evaluated with OIL, showing significantly improved data transmission performance [76].…”

“…Using VCSEL as both master and slave lasers, Lu demonstrated 45 Gb/s PAM4 transmission [74]. Although the experiment was based on free-space coupling, a potential of integrating two VCSELs vertically may help to overcome the bandwidth bottleneck of the VCSEL [74], [75]. A more recent research reports OIL to microring lasers [76], obtaining high side mode suppression ratio (SMSR) of up to 56 dB with intrinsic modulation bandwidth increased from 3 GHz to 18 GHz for different longitudinal modes across a 30 nm wavelength range.…”

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.

Communication involves exchange of data between sender and receiver. The data exchange complexity reduce with wireless data transmission. Conventionally radio signals use for wireless data transmission. The radio frequency limited band width and requirement of new hardware installation make LIFI an optimal solution for wireless data transmission. Since the existing LEDs can be used for data transmission. Recent trends in LiFi have made it possible to transmit data at THz frequency. However, the LiFi signals easily degrade due to surrounding environment noise. In this paper, we propose to reconstruct and eliminate noise in LiFi signal. Wave coefficient block apply for noise level estimation and filter banks use to reconstruct original message signal.

“…Thereby, adopting an injection locking scheme at the transmitting site and a linear equalizer at the receiving site are expected to perform well in a high-speed vestigial sideband (VSB)-PAM8 verticalcavity surface-emitting laser (VCSEL) transmitter-based fiber-IVLLC integration. A previous study revealed the practicality of setting up a 56 Gb/s four-level pulse amplitude modulation (PAM4) LiFi transmission on the basis of VCSEL transmitter with two-stage injection locking scheme [7]. Another previous study demonstrated the feasibility of building a 64 Gb/s PAM4 free-space optical (FSO) link on the basis of VCSEL transmitter with injection locking scheme [8].…”

A high-speed 84 Gb/s vestigial sideband (VSB)-eight-level pulse amplitude modulation (PAM8) fiber-invisible laser light communication (IVLLC) integration based on vertical-cavity surface-emitting laser (VCSEL) transmitter with injection locking scheme is proposed. To the authors' knowledge, this study is the first to realize a high-speed 84 Gb/s VSB-PAM8 VCSEL transmitter-based fiber-IVLLC integration. It is effectual to adopt an optical VSB-PAM8 signal in fiber-IVLLC integrations to suppress the linewidth of an optical signal so as to reduce the fiber dispersion. An injection locking scheme and a linear equalizer possess enhancements in frequency response, and thereby provide good transmission performances in a high-speed VSB-PAM8 fiber-IVLLC integration. Impressive bit error rate performance and clear eye diagrams are acquired in real time at a 25-km single-mode fiber operation with a 10-m free-space link. Such proposed 84 Gb/s VSB-PAM8 VCSEL transmitter-based fiber-IVLLC integration is a notable option for providing high transmission rates at optical fiber and optical wireless communications.
