Integrated Optical Circuit (IOC) is the integration of LDs, PDs, modulators, gate couplers, waveguides and other optoelectronic components into a single chip. Although the concept of integrated optics was first proposed by Bell Labs in the USA in 1969, it was not until the last decade that there was a breakthrough in the technology. There is a wide range of materials used in the production of these ICs, including lithium niobium, silicon, silicon nitride, gallium arsenide, phosphor, optical glass, and polymers, with silicon and phosphor being the main focus of current research. Mordor Intelligence, a market research organization, estimates that the global integrated optical circuit market will reach $15.11 billion in 2024 and will grow to $38.35 billion in 2029, with an average compound annual growth rate of 20.47%, with Alcatel-Lucent, Avago (Broadcom), Cisco, Cisco, and Avago as the leading vendors, Cisco,
