What is Photonics? – An Enabling Technology

What Is Photonics?

Photonics is the technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. Photonics involves cutting-edge uses of lasers, optics, fiber-optics, and electro-optical devices in numerous and diverse fields of technology – alternate energy, manufacturing, health care, telecommunication, environmental monitoring, homeland security, aerospace, solid state lighting, and many others.

Why Is Photonics Important?

Lasers and other light beams are the “preferred carriers” of energy and information for many applications. For example:

  • Lasers are used for welding, drilling, and cutting of metals, fabrics, human tissue, and other materials.
  • Coherent light beams (lasers) have a high bandwidth and can carry far more information than radio frequency and microwave signals.
  • Fiber optics allow light to be “piped” through cables.
  • Spectral analyses of gases and solid substances provide positive identification and quantifiable concentrations.

The applications of photonics as an “enabling” technology are extremely broad. From an educational standpoint, this means that the infusion of one or two photonics courses into two-year postsecondary programs in related technologies can qualify graduates for a far wider variety of jobs and increase the global competitiveness of the American workforce.

Projected Demand for Workers in Photonics-Enabled Technologies

Rapid growth in the number and complexity of photonics and photonics-enabled technologies has caused the demand for technicians to exceed supply. The number of college degrees in engineering is decreasing, causing fierce competition for the relatively small pool of qualified optics technicians and engineers. A recent survey of employers showed that the number of U.S. technical jobs in photonics and photonics-enabled technologies is expected to grow more than 800 per year on average through 2017. Clearly, the current supply of qualified graduates of two-year postsecondary programs falls far short of industry demand.

Photonics-Enabled Fields

  • Aerospace technology – Uses LiDAR (laser RADAR systems) and laser altimeters, imaging systems for test and analysis of aircraft, holographic heads-up displays, and optical pattern recognition systems for navigation
  • Agriculture – Uses satellite remote sensing to detect large-scale crop effects, scanning technology and infrared imaging to monitor food production and quality, and sensor systems for planting and irrigation
  • Biomedicine – Uses lasers for surgery, therapies such as photodynamic therapy, and in situ keratomileusis (LASIK) procedures; uses testing and analysis devices such as noninvasive glucose monitors
  • Construction – Includes scanning site topography, laser bar-code readers to inventory materials, laser distance measuring and alignment, and three-dimensional analysis to track the progress of construction
  • Engineering, microtechnology, and nanotechnology – Uses lasers in the manufacture of electrical devices, motors, engines, semiconductor chips, circuits, and computers; via photolithography, photonics is central to MEMS production
  • Alternate Energy / Green Solutions – Photovoltaic Devices (PVDs) are used for Solar Electric Panels. Recent improvements in cost, efficiency, and reliability promise that PVDs will be an even greater contributor to Alternative Electric Energy in the future.
  • Environmental technology – Uses ultraviolet Doppler optical absorption spectroscopy (UV-DOAS) to monitor air quality; uses fast Fourier transform analysis to monitor particulate matter in effluents released from stacks
  • Geographic information systems and global positioning – Uses optics and photonics in imaging and image processing to refine atmospheric and space-based images
  • Information technology – Uses optics for data storage, ultrafast data switching, and (especially) transmission of data across fiber-optic networks
  • Chemical technology – Relies on molecular optical spectroscopy for analysis and on ultra-short laser pulses to induce fluorescence; chemical vapor deposition and plasma etching support photonics thin film applications
  • Transportation – Uses optics for monitoring exhaust emissions to ensure the integrity of shipping containers arriving from foreign ports, and navigation with ring laser gyroscopes
  • Homeland security – DNA scanning, laser forensics, retinal scanning, identification of dangerous substances, optical surveillance
  • Manufacturing – Laser welding, drilling, and cutting; precision measurements
  • Biotechnology – Optical spectrometers and other optical devices are being used to verify biochemical compositions and monitor biotech processes.
  • Solid State Lighting – Light-Emitting Diodes (LEDs) are replacing incandescent bulbs because of their low efficiency and compact fluorescent lighting (CFLs) because of their exposure of mercury to the environment. The cost of LEDs for outdoor lighting, traffic lights and indoor commercial and office use is now cost effective.
