Silicon photonics market to hit US$6.1 billion by 2030


Silicon photonics revolutionizes data transmission, offering high-speed efficiency for data centers, telecom, and emerging technologies.

Silicon photonics is a cutting-edge technology that integrates optical devices and circuits onto a single silicon substrate. Its primary goal is to boost data transmission speeds and efficiency by harnessing the benefits of optical communication within traditional silicon-based electronic circuits. This integration allows for the creation of high-performance communication systems, providing faster data transfer rates and reduced energy consumption compared to conventional electronic connections. The global silicon photonics market is forecast to expand at a CAGR of 22.4% and thereby increase from a value of US$1.4 Billion in 2023, to US$6.1 Billion by the end of 2030.

In the realm of silicon photonics, major driving forces include the escalating demand for high-speed data transmission in sectors like data centers, telecommunications, and cloud computing. Its capacity to address the limitations of conventional electronic connections, including bandwidth constraints, positions it as a compelling solution for emerging applications.

Additionally, the increasing emphasis on energy-efficient communication solutions and the necessity for higher bandwidth contribute to the market's favorable prospects. Opportunities are abundant in the advancement of sophisticated silicon photonics components, expanding applications in emerging technologies, and the ongoing evolution of data-intensive industries. These elements firmly establish silicon photonics as a pivotal player in the future of high-speed and energy-efficient communication systems.

Increasing Demand for CMOS-Integrated Silicon Photonics in Data Centers

The rising demand for CMOS-integrated silicon photonics technology in data centers stems from its ability to address challenges related to high-speed data transmission (>100 Gbps) and energy efficiency. By combining the power of optical communications with the cost-effectiveness and scalability of CMOS technology, silicon photonics has become an attractive solution for data center operators. Modern data centers globally require next-generation data storage systems and high-speed data transfer rates. Datacom protocols are transitioning to high-speed signaling, exceeding 100 Gbps, leading to challenges related to range and signal integrity for both copper and optical cables. As a result, the need for low-cost, power-efficient, high-bandwidth interconnection networks becomes crucial for data centers. Silicon photonics technology can seamlessly integrate with traditional complementary metal-oxide semiconductor (CMOS) devices to meet the demand for next-generation performance in data centers, especially for interconnects supporting data rates beyond 100 Gbps. This factor fuels the growth of the silicon photonics market.


Thermal Effects

Thermal effects pose a significant concern in the Silicon Photonics industry, especially as devices become smaller and more intricate. These effects occur due to the absorption of light by silicon, leading to increased device temperatures. Elevated temperatures can result in reduced device performance or even device failure. Integration of electronic and photonic components on the same chip exacerbates this issue, as heat generated by electronic components can impact photonic components and vice versa. Additionally, high-powered laser sources can generate substantial heat, potentially causing thermal damage to the device. Silicon photonics finds extensive use in telecommunication and data communication servers, which consume high power and introduce thermal stress. For example, increased temperature can alter the refractive index of optical light, resulting in data loss. Currently, the impact of this restraint is moderate, but innovative packaging technologies, such as liquid-crystal cladding with a negative thermo-optic coefficient and low absorption at infrared wavelengths, are expected to mitigate this concern in the near future.

Emerging Applications of Silicon Photonics

While datacom and telecom remain major applications of silicon photonics, recent efforts by research institutes and industry players have focused on exploring opportunities in other areas, such as medical and life sciences, and automotive LiDAR. Automotive LiDAR plays a crucial role in autonomous vehicles, with research groups like MIT Photonics Microsystem Group and DARPA working on integrating mechanical LiDAR systems onto microchips for mass production in CMOS foundries. Silicon photonics is poised to revolutionize the medical diagnosis industry, offering high-speed kits for home and laboratory settings and point-of-care testing. Its speed, accuracy, versatility, and size make silicon photonic biosensors capable of evaluating various analytes efficiently. As global health data increasingly relies on imaging data from laboratories, hospitals, and imaging centers, high-speed data transmission channels will be essential, and silicon photonics technology is well-suited to fulfill this need.


Inefficient Electroluminescence of Bulk Crystalline Silicon

For optical networks, including fiber-optic and on-chip applications, light sources are essential components. Bulk crystalline silicon exhibits inefficient electroluminescence, making the development of practical silicon light sources a primary focus of research and development efforts. Silicon lasers and amplifiers are valuable in silicon photonics; however, they require intense optical pumping, which may need to occur off-chip. Nevertheless, significant progress is being made in developing Si-based sources, which are expected to enter the market in the next five years to address on-chip optical pumping challenges.
