Silicon Photonics Market Growth is Driven by High Volume Production at Low Costs by Leveraging CMOS-like Fabrication

 Market Insights:

Silicon had dominated the electronics sector for several decades before it became a potential material of choice across the photonics industry. Silicon photonics took off back in 2004, boosted by industry and governmental investments. After a series of breakthroughs and rising investments, silicon photonics is now considered the most active discipline in the integrated photonics field. Silicon, as a photonic material, does have some shortcomings. It is not an ideal material in its basic form; thus, numerous research projects have, in the past decade, addressed this and other such concerns, and with time, novel solutions are being formulated. 

Recently, Laura Lechuga, an OSA Fellow, and her team at Catalan Institute of Nanoscience and Nanotechnology, Spain, were awarded the European Union funding for developing a point-of-care (PoC) nanophotonic biosensor that can detect the presence of SARS-CoV-2, the virus responsible for the COVID-19 infection. The group has been using up to 20 biosensors on a chip to design silicon photonics devices.

The key element driving the adoption of the silicon photonics market is the high-volume production at low costs it offers by leveraging CMOS-like fabrication. It has played a major role in bringing photonics to a wide array of technology sectors, wherein the cost of implementation would have been too high when using traditional photonic elements like the ones employed in the telecommunications industry.  The field of silicon photonics has also gained traction because it enables the making of optical devices inexpensively through semiconductor fabrication technology. 

Significant factors propelling the silicon photonics market forward are the surging demand from data centers for cloud computing and the escalating usage of internet. Government initiatives to push the adoption of online transactions and e-banking would also be beneficial for the adoption of the silicon photonics market in the future. Even with these drivers fostering market growth, challenges such as the advent of alternative technologies and high-volume markets might create some hurdles in the widespread implementation of the technology.

The leading companies in the industry include AIO Core Co. Ltd, Cisco Systems, Inc., Hamamatsu Photonics K.K., IBM Corporation, Infinera Corporation, Intel Corporation, IPG Photonics Corporation, Mellanox Technologies Ltd, NKT Photonics, and STMicroelectronics NV. This month, Rockley Photonics closed an additional USD 50 million funding round from VCs, institutional funds, and strategic investors, including Applied Ventures, the VC wing of Applied Materials, and Credit Suisse-backed SIG-i, along with the current shareholders. The latest round brought Rockley’s total funds raised to USD 225 million, allotted to developing its silicon photonics platform. 

Both existing and emerging companies are striving to optimize the potential of the technology and get a competitive edge in the silicon photonics industry. Photonics-based computing requires less energy and is also able to transfer data much faster than traditional techniques and will help market growth, although manufacturing costs of silicon integrated circuits with embedded photonic elements can be prohibitive, which poses a substantial challenge. 

Scientific and Technological Advancements will Open New Avenues For Quantum Cascade Laser Market

Market Insights:

Quantum Cascade Lasers (QCLs) operate from MIR (mid-infrared) range to terahertz. The fingerprint region of the MIR range is vital in the field of spectroscopy. Unlike other technologies, like the FTIR spectroscopy, wherein the sample is simultaneously exposed to the entire available wavelength, QCL gives the option of tuning it to individual wavelengths, enabling alternative modes of operation. QCL operates at speeds and wavelength accuracy that are significantly better than that of FTIR. 

Terahertz lasers are being studied profusely owing to their ability to penetrate ubiquitous packaging materials like fabrics, cardboard, and plastics, and can also help detect and identify a variety of chemicals as well as biomolecular species. They even work for imaging of several kinds of biological tissue, as they also do not cause any damage. To unlock their full potential, it was necessary to enhance their brightness and intensity, which can be accomplished by increasing the beam quality and power output. A recent study by a team from Lehigh University found a simple yet efficient way to increase the power output of single-mode by employing a novel kind of “distributed-feedback” mechanism. It was a major breakthrough in the field and garnered a lot of attention for QCLs. The scientific and technological advancements will open new avenues for the market, propelling its growth in the future. 

Even with their extensive use as a semiconductor laser and in collision avoidance radar, industrial process control LIDAR, and automotive cruise control, ever-changing consumer demands and cost of QCLs might impede the adoption rate, thereby hindering the growth of the market. The leading companies in the market are well-equipped with large manufacturing facilities and are investing in research & development activities. Some of the prominent QCL players are Alpes Lasers SA, Emerson Electric Corporation, Hamamatsu Photonics K.K., Mirsense, Wavelength Electronics, Inc., Akela Laser Corporation, Block MEMS, Thorlabs, Inc., Nanoplus Nanosystems and Technologies GmbH, and Adtech Optics.

Swiss company Alpes Lasers recently announced that it is working with on a new laser-based sensor to detect traces of toxic substances in wastewater in collaboration with some a team of European scientists. Researchers from the company have teamed up with academic institutes and oil industry partners to develop an ultrafast sensor capable of detecting the “tiniest concentrations” of suspended solids and oil in wastewater with Frequency Comb Quantum Cascade Lasers. The broadening application scope of the technology is attracting companies to invest in new projects and will foster the growth of the market across the globe.
