“…Semiconductor optical amplifiers are one to two orders of magnitude more resistant to radiation than fiber optic amplifiers, without any special improvements in radiation resistance [9][10][11][12][13][14]. High-power, low-cost, and integrated SOA devices are eminently suitable for carrying space loads for space laser communication.…”

The 1550 nm band semiconductor optical amplifier (SOA) has great potential for applications such as optical communication. Its wide-gain bandwidth is helpful in expanding the bandwidth resources of optical communication, thereby increasing total capacity transmitted over the fiber. Its relatively low cost and ease of integration also make it a high-performance amplifier of choice for LiDAR applications. In recent years, with the rapid development of quantum-well (QW) material systems, SOAs have gradually overcome the shortcomings of polarization sensitivity and high noise. The research on quantum-dot (QD) materials has further improved the noise characteristics and transmission loss of SOAs. The design of special waveguide structures—such as plate-coupled optical waveguide amplifiers and tapered amplifiers—has also increased the saturation output power of SOAs. The maximum gain of the SOA has been reported to be more than 21 dB. The maximum saturation output power has been reported to be more than 34.7 dBm. The maximum 3 dB gain bandwidth has been reported to be more than 120 nm, the lowest noise figure has been reported to be less than 4 dB, and the lowest polarization-dependent gain has been reported to be 0.1 dB. This study focuses on the improvement and enhancement of the main performance parameters of high-power SOAs in the 1550 nm band and introduces the performance parameters, the research progress of high-power SOAs in the 1550 nm band, and the development and application status of SOAs. Finally, the development trends and prospects of high-power SOAs in the 1550 nm band are summarized.

We present data from localized heat inducement studies at both cellular and tissue levels along with a computational model built to predict the temperature increase and damage extent in tissues receiving hyperthermia treatment by a fiber-based active heater. This novel fiber-based active heater serves as a heat source and a temperature sensor. Five important insights are highlighted from this thesis work.First, heat-induced controlled cell deaths were observed experimentally in the three cell lines with MCF-10A being more susceptible to heat compared to HEK 293 and MCF7 cells. Second, comparison between the phantom tissue and ex vivo experimental and computational results shows a lesion size of 5×12 mm and 4.87×11.6 mm in the phantom tissue and 7×15 mm and 8.8×14.3 mm in the ex vivo studies at pumping power of 1.8 W for 10 minutes respectively. Thus, this computational model is able to provide information about the heat transfer characteristics caused by the active heater in living biological tissue.
