Optical Design & Engineering
Laser communication between fast-flying platform and ground station
Transmitter and receiver terminals for aeronautical optical communications were developed and a laser link between a jetfighter and a ground station was demonstrated.
Measuring the phase shifts produced by transmissive spatial light modulators
A new technique enables phase shifts to be determined by measuring the fringe shifts in recorded interferograms.
Detecting phase transitions in an optical microcavity
Changes in the whispering gallery mode resonance of liquid crystal droplets offer insight into their internal ordering.
Using carbon nanotubes to make smart telescope mirrors
Smart materials enable fabrication of lightweight, compact optical mirrors that can be replicated at low cost for use in large space telescopes.
Diffractive optics technologies further advance photonic systems
Advances in the field of diffractive optics enable imaging systems with reduced size and weight and could provide controllable structured field distributions for use in sensors and displays.
Lens-free microscopy on a chip
A fully integrated, customizable, and mass-producible microscope-on-chip uses integrated photonics to implement its compact and high-quality coherent illumination subsystem.
Miniature droplet lenses for mobile microscopy
Harnessing millimeter-sized liquid droplets enables fabrication of high-power solid lenses of varying focal lengths for use in mobile devices.
