“…Below that power, a high impact of the seed on the output power is visible, while above the slope remains almost constant with the seed power. To saturate the amplifier results in a high efficiency for the stimulated emission, reducing the spontaneous emission and improving the side mode suppression ratio (SMSR) [8].…”

Semiconductor master-oscillator power-amplifiers (MOPAs) are versatile tools for various applications. We will present high-power (P > 5 W), high-coherence length (Lc > 100 m), small-sized (L ≤ 25 mm), hybrid semiconductor MOPAs at 920 nm, 976 nm, 1030 nm, 1064 nm, 1120 nm, and 1154 nm. We compare their performance to corresponding distributed Bragg reflector tapered laser and discuss strategies to extend the wavelength range.

“…Parametric amplifiers serve to minimise the noise and thus improve the reach of data in advanced modulation formats. Our group has demonstrated the potential of using Semiconductor Optical Amplifiers (SOA) for coherent communication, especially useful in the context of ultra-wideband amplification [26]. Figure 2 shows the results for 16/64 QAM when SOA is used as inline amplifier in coherent communication link.…”

“…Figure 2 shows the results for 16/64 QAM when SOA is used as inline amplifier in coherent communication link. The distortions incurred while amplification are mitigated by employing a strong beam called holding beam (Hbeam) [26]. In addition, compact semiconductor optical amplifiers are also demonstrated to be used as spectral inverters for dispersion healing in the optical domain, which can in turn minimise the requirements on digital signal processing [27].…”

With the increasing use of internet and mobile phones, the capacity of the backbone optical communication link has been continually growing across the world and especially in India. The total optical fiber cable deployed for the BharatNet initiative of Government of India is expected to increase from 3.4 million km to 5 million km in 2024-25 just for providing lastmile connectivity. Considering this deep proliferation, this article attempts to capture the diverse research carried out in India in the domain of optical communication.

“…Most of the work completed so far on all-optical signal regeneration has exploited the nonlinear properties of optical fibers [ 178 , 179 ] or semiconductor optical amplifiers (OAS) [ 180 , 181 , 182 ]. Figure 14 shows the experimental setup for characterization of a polarization-independent differential phase shift keying (DPSK) regenerative wavelength converter [ 181 ].…”

The combination of integrated optics technologies with nonlinear photonics, which has led to growth of nonlinear integrated photonics, has also opened the way to groundbreaking new devices and applications. In a companion paper also submitted for publication in this journal, we introduce the main physical processes involved in nonlinear photonics applications and discuss the fundaments of this research area. The applications, on the other hand, have been made possible by availability of suitable materials with high nonlinear coefficients and/or by design of guided-wave structures that can enhance a material’s nonlinear properties. A summary of the traditional and innovative nonlinear materials is presented there. Here, we discuss the fabrication processes and integration platforms, referring to semiconductors, glasses, lithium niobate, and two-dimensional materials. Various waveguide structures are presented. In addition, we report several examples of nonlinear photonic integrated devices to be employed in optical communications, all-optical signal processing and computing, or in quantum optics. We aimed at offering a broad overview, even if, certainly, not exhaustive. However, we hope that the overall work will provide guidance for newcomers to this field and some hints to interested researchers for more detailed investigation of the present and future development of this hot and rapidly growing field.
