Capitalizing on Optical Science Trends and Challenges for Future Research undertook a new study to examine the current state of the art and economic impact of optics and photonics technologies, with an eye toward ensuring that optics and photonics continue to enable a vibrant and secure future for U.
Optics and photonics, an enabling technology with widespread impact, exhibits the characteristics of a general-purpose technology, that is, a technology in which advances foster innovations across a broad spectrum of applications in a diverse array of economic sectors. Improvements in those sectors in turn increase the demand for the technology itself, which makes it worthwhile to invest further in improving the technology, thus sustaining growth for the economy as a whole.
The transistor and integrated circuit are good examples of general-purpose technologies. The importance of photonics as an enabling technology since can be highlighted by a few examples:. The most obvious contribution of optics is the high-resolution display and the camera. In addition, the cell phone uses a wireless radio connection to a local cell tower, and the signal is converted to an optical data stream for transmission along a fiber-optic network.
An Internet search conducted on the phone will be directed over these fibers to a data center, and in a given data center clusters of co-located computers talk to each other through high-capacity optical cables. There can be more than 1 million lasers involved in the signaling. For example, nearly every microprocessor has been fabricated using optical lithographic techniques, and in nearly all advanced manufacturing, high-power lasers are used for cutting and welding.
Swallowed capsules can travel through the body and send images back to a doctor for diagnosis. Today, the relatively young field of optical coherence tomography has the potential. Optical spectroscopic techniques can provide valuable information from blood and tissue samples that is critical in early detection and prevention of health problems, and eye, dental, and brain surgery now uses focused lasers for ablating, cutting, vaporizing, and suturing.
Although the Thanh Hoa Bridge withstood sorties by conventional bombs and 11 U. In Iraq and Afghanistan, smart bombs are the norm. Moreover, situational awareness of the battlefield and of enemy terrain provides information for targeting. Additional examples of optics and photonics as enabling technologies are discussed in subsequent chapters and also in Appendix C.
From an economic standpoint, an enabling technology like optics and photonics tends to be commercialized outside the industry, and profits can be generated by companies that do not consider themselves a part of the photonics industry. These companies are more inclined to invest in previously validated applications for which photonics can but does not necessarily provide the sole technology solution, rather than to invest in photonics in particular. Since , the photonics industry has tended to receive little interest from the investment community and little financial analyst coverage, and start-up companies in photonics can have difficulty acquiring seed capital.
In considering actions for global leadership in the photonics industry, the committee took note of several important points. For example, although many key optics and photonics innovations occurred in the United States, including in display and communications technologies, the multibillion-dollar display industry has moved mostly to Southeast Asia, with a negligible fraction of display production remaining in the United States.
Furthermore, whereas the United States for decades led the manufacture of telecommunications equipment, China went from having no company in in the top 10 largest telecommunications companies in the world to having three such companies in A similar scenario exists for Chinese companies that specialize in selling optical components and subsystems. By contrast, data centers continue to be located overwhelmingly in the United States, possibly because the United States has the most effective communications infrastructure at the moment.
A theme evident in several of the presentations made to the committee was that innovation will remain critical to ensuring a U. The United States has acclaimed educational institutions and a creative, entrepreneurial corporate spirit. According to the U. Patent and Trademark Office, the number of patents granted to the United States in in the field of optics was more than 50 percent greater than that granted to the next-nearest country.
Yet, according to the records of the Optical Society of America, the number of research papers submitted to its journals in by scholars from the Pacific Rim countries exceeded the number of papers submitted by North American authors.
Education plays a critically important role in ensuring a vibrant future for the United States in the fields of optics and photonics. Today, the United States has. An Enabling Technology , for fields that are important. A new journal in optics and photonics— Light: Science and Applications 1: Accessed July 26, Over the past several years, many institutions outside the United States have also invested heavily in excellent educational facilities.
Because education is inextricably linked to innovation in optics and photonics, the committee underscores the importance to the nation of maintaining a strong U. Although the present study does not focus on education, it does mention specific examples that might benefit from action, including the training of skilled technicians as well as ensuring that an adequate numbers of citizens can be hired by the defense industry. The committee concluded that improvements in technical education are needed to increase the quality of skilled blue-collar workers in optics and photonics.
Although many of the innovations in optics and photonics i. The committee has heard compelling arguments that, if the United States does not act with strategic vision, future scientific advances and economic benefits might be led by others. Optics and photonics technologies are ubiquitous: The opportunities arising from optics and photonics offer the potential for even greater societal impact in the next few decades, including solar power generation and new efficient lighting that could transform the nation's energy landscape and new optical capabilities that will be essential to support the continued exponential growth of the Internet.
Essential Technologies for our Nation , it is critical for the United States to take advantage of these emerging optical technologies for creating new industries and generating job growth. The report assesses the current state of optical science and engineering in the United States and abroad--including market trends, workforce needs, and the impact of photonics on the national economy. It identifies the technological opportunities that have arisen from recent advances in, and applications of, optical science and engineering. The report also calls for improved management of U.
Essential Technologies for our Nation is a useful overview not only for policymakers, such as decision-makers at relevant Federal agencies on the current state of optics and photonics research and applications but also for individuals seeking a broad understanding of the fields of optics and photonics in many arenas.
