Atmospheric Structure and LIDAR
What is the added value of lidar for
Arecibo Observatory?
• The ISR is sensitive to ions
• The lidar is sensitive to neutral atoms and
molecules, and one specific ion can be studied –
Ca+
• Airglow can study specific height ranges, lidar can
probe inside and outside those ranges.
• Under certain circumstances, lidar and radar, lidar
and airglow, or all three can study the same
parameters. This allows confirmation (or not) of
measurements.

The Puerto Rico Photonics Institute
• The only center for photonics research,
development, education and training in
Puerto Rico.
• A magnet for industry
• A partner for research and education
Arecibo Observatory – 31 May 2013
What is Photonics
• Photonics is the manipulation of light for
technology development, science, and other
applications.
• It is used in Communications, navigation,
displays, remote sensing, biotech, medical
devices, defense, security, energy,
astronomy, space weather, computing,
lighting, materials processing, environment,
transportation, entertainment, computeraided design…
Arecibo Observatory – 31 May 2013
What tools does Photonics Employ?
• Lasers of all types (from DVD players to welding)
• Fiber optics
• Sensors, such as CCDs (a gift from
astronomy)
• Electronics, to connect optical signals to
devices
• Optical components (lenses, mirrors, etc.)
Arecibo Observatory – 31 May 2013
Photonics as a Career
• Fast-growing technologies ⇒ Workforce
needs
• Fascinating work ⇒ Lasers, sensors, metamaterials, holograms, fibers, spectrum
generation …
• High salaries ⇒ Orlando, FL photonics
companies pay >$40k/year for technicians
with AAS degrees & little experience
Arecibo Observatory – 31 May 2013
What is the Puerto Rico Photonics
Institute (PRPI)?
• The only center for photonics research,
development, education and training in
Puerto Rico.
• A magnet for industry
• A partner for research and education

Research
• Current
– Remote Sensing ⇒ LIDAR at Arecibo, elsewhere
– Aerospace Photonics ⇒ Laser gyroscopes for
navigation and sensors
• Future
– Space Weather ⇒ Monitoring stations, prediction
center
– High power lasers
– Biophotonics ⇒ A hot field. We will look to add
this to our research portfolio.
