Fiber-optic Frequency Comb Development

Ongoing
To support comb-based measurements outside the metrology laboratory, we develop high performance, robust frequency combs based on fiber-optic technology.

GaN Nanowire Growth

Ongoing
GaN nanowires grown by catalyst-free molecular beam epitaxy have the unique property that most nanowires are completely free of crystalline defects. This

High-Power Laser Applications

Ongoing
High power lasers capable of continuous output powers ranging from hundreds of watts to tens-of-thousands of watts present exciting opportunities for rapid

Nanostructure Fabrication and Metrology

Ongoing
Single photons are the fundamental particles for all optical measurements. Single photon detectors made from avalanche photodiodes or photomultiplier tubes are

Nanostructure Synthesis

Ongoing
We synthesize semiconductor nanostructures to serve both as test structures for measurement techniques and as building blocks for novel metrology tools and

Photonic Radiometry

Ongoing
Accurate characterization of photonic equipment is important for optical communications, medical devices, semiconductor lithography, manufacturing and materials

Quantum Radiometry Project

Ongoing
Calibrated and characterized single photon sources and detectors are building blocks of the infrastructure required to achieve widely used, industrialized

Super-Continuum Laser Solar Simulator

Completed
This research leverages a new laser technology, the super-continuum laser, to produce a programmable solar simulator that can rapidly configure to match nearly

Terahertz Imaging and Sources

Ongoing
Imaging in the terahertz frequency range enables the detection of concealed weapons and other contraband (e.g., explosives under clothing) without the use of

Waveform Metrology Project

Ongoing
Today's economy relies on high-speed communications that ride fiber-optic networks, and CTL physicists play a crucial role in providing the means to test the
